Mastering APIs with a Simple Restaurant Analogy By Dhanian | Author of How APIs Work: The Invisible Force Behind Modern Apps APIs power nearly every app you use today—from weather updates to payment systems. But what is an API, and how does it work? Let’s break it down using a familiar setting: a restaurant. This analogy will help you visualize the invisible magic behind software communication. An API (Application Programming Interface) is a bridge that allows two systems to communicate. Think of it as a messenger that delivers your request to a system and returns the response back to you. In software terms: The client (like your app or browser) wants something. The API receives the request and talks to the server. The server sends back data via the API. restaurant to understand how APIs …  ( 4 min )

At first, I didn’t really understand what the purpose of the layers in Tailwind’s CSS system was.

Recently, on LinkedIn, I've been seeing the posting from Duolingo's team about how they have decided to do away with the whole UX wireframing process. While that might sound rather controversial to most folks, as an experienced professional, I actually do kinda understand where they might be coming from. You must understand that I've been drawing UX wireframes since early 2006. That's almost two decades now. I've done so many wireframes that by now, a lot of what I can do on paper using sketches or even the digital form, I can mentally visualize them inside my head, and I can convert most of them smoothly into UI prototypes.

The US government has asked a federal judge to impose a two-year sentence for Eric Council Jr., the individual who helped post a fake message announcing the approval of Bitcoin exchange-traded funds through the Securities and Exchange Commission’s (SEC’s) X account. In a May 12 filing in the US District Court for the District of Columbia, prosecutors recommended Judge Amy Berman Jackson sentence Council to two years in prison for his role in posting a message to the social media platform X suggesting that the SEC had approved spot Bitcoin (BTC) exchange-traded funds (ETFs) for the first time in January 2024. The fake announcement, which shook markets in the roughly 24 hours before the regulator actually approved spot Bitcoin ETFs, led to the arrest of Council. “This case deserves a guideli…

Key takeaways: Bitcoin lags as investors shift toward stocks after the US and China strike a deal that could end the current trade war. Macroeconomic conditions are swinging away from gold investing and back to stocks.  Bitcoin (BTC) reached its highest price in over three months at $105,720 on May 12, but was unable to maintain its bullish momentum. Interestingly, the drop to $102,000 came after a temporary easing in the US-China tariff conflict. This has left traders puzzled as to why Bitcoin reacted negatively to what seemed like positive developments. The 90-day truce reduced import tariffs, and US Treasury Secretary Scott Bessent noted that the agreement could be extended, provided there is a genuine effort and constructive dialogue. According to Yahoo Finance, the topics under dis…

Opinion by: Robin Singh, CEO of Koinly Is there a catch for Bitcoin hodlers, with the asset’s price up over 600,000% since the beginning of 2013?  Perhaps — if governments keep waking up to Bitcoin’s value, the whole “you only pay tax when you sell” mantra could soon be a thing of the past. What if a wealth tax is the answer for revenue-hungry tax agencies with no time to lose? It’s a yearly tax on a person’s total net worth — cash, investments, property and other assets — minus any debts, applied whether or not those assets are sold or generating income. The idea is to boost public revenue and curb inequality, mainly by taxing the ultra-rich. A wealth tax takes a clip off what you own, not what you earn. Countries such as Belgium, Norway and Switzerland have had wealth taxes baked into th…

We do want trade. We want more balance in trade.” Joint statement on US-…

What is RISC-V? RISC-V, pronounced “risk five,” is a modern open-source instruction set architecture (ISA) based on reduced instruction set computer (RISC) principles. In simple terms, it’s like a blueprint that defines a set of instructions that a processor can execute. RISC-V is designed to be highly modular, efficient and flexible. Originally developed by the University of California in 2010, the open-source framework gives developers the flexibility to tailor its functionality and use cases, plus offers cost savings compared to proprietary ISAs like ARM or x86.

Social engineering in crypto, explained In the world of cryptocurrency, security goes beyond just protecting your wallet with a password or private key. One of the most deceptive and increasingly dangerous threats to crypto users today is social engineering. While you might think of cyberattacks as highly technical affairs, social engineering manipulates the most vulnerable aspect of security: human nature.  At its core, social engineering refers to the act of manipulating people into divulging confidential information or granting unauthorized access to systems.  Unlike traditional hacking, which typically exploits technological vulnerabilities, social engineering targets the human element.

Key takeaways Though Bitcoin doesn’t support native staking, holders can earn yield through centralized lending platforms, Wrapped Bitcoin (WBTC) on Ethereum, and Bitcoin-related networks like Babylon and Stacks. WBTC allows BTC holders to participate in lending, liquidity pools and yield farming on Ethereum-based DeFi platforms like Aave and Curve but introduces bridge and smart contract risks. Protocols like Babylon and Stacks use mechanisms like native time-locked scripts or stacking to offer rewards without removing BTC from the Bitcoin blockchain. Custodial, smart contract and regulatory risks persist. Bitcoin’s community also remains divided on whether Bitcoin yield generation features align with its decentralized and trust-minimized ethos. Unlike proof-of-stake (PoS) blockchain…

Bitcoin’s potential price reaction to a trade deal between the United States and China could give insights into whether Bitcoin is being used as a safe-haven asset in the current market.

On May 9, the Northern Mariana Islands Senate voted 7-1 to override Governor Arnold Palacios' April 11 veto of the bill, which would allow the Tinian local government to issue licenses to internet casinos and includes a provision for the Tinian treasurer to issue, manage and redeem a “Tinian Stable Token.”  The bill will now head to the 20-member Northern Mariana Islands House, which will need a two-thirds majority vote to override the veto and pass the bill into law. If the House is quick to pass the bill, the Tinian government could be in the lead for the first US …

Censorship-resistant “dark stablecoins” could come in increasing demand as governments tighten their oversight of the industry.  Stablecoins have been used for various groups to store assets due to a lack of government interference; however, with regulations pending, that could soon change, Ki Young Ju, CEO of crypto analytics firm CryptoQuant, said in a May 11 X post. “Soon, any stablecoin issued by a country could face strict govt regulation, similar to traditional banks. Transfers might automatically trigger tax collection through smart contracts, and wallets could be frozen or require paperwork based on government rules,” he said. “People who used stablecoins for big international transfers might start looking for censorship-resistant dark stablecoins instead.” On the heels of US Presi…

Hardware wallet provider Ledger has confirmed its Discord server is secure again after an attacker compromised a moderator’s account to post scam links on May 11 to trick users into revealing their seed phrases on a third-party website. “One of our contracted moderators had their account compromised, which allowed a malicious bot to post scam links in one channel,” Ledger team member Quintin Boatwright wrote on the Ledger Discord server.  “The issue was quickly contained: the compromised account was removed, the bot was deleted, the website was reported, and all relevant permissions were reviewed and secured.” Some members in Ledger’s Discord channel claimed the attacker abused moderator privileges to ban and mute them as they tried to report the breach, possibly slowing Ledger’s reaction.…

Let’s be honest: most cloud “strategies” I come across aren’t really strategies — they’re glorified lift-and-shifts. On paper, migrating to the cloud promises flexibility, scalability, and cost savings. But in reality? Many organizations just copy their on-prem setup into AWS, Azure, or GCP — and call it done. As someone who’s spent years helping companies build scalable, secure, and cloud-native infrastructure across multi-cloud environments, I’ve seen this mistake over and over. But one project in particular made this painfully clear. The Lift-and-Shift That Didn’t Shift Anything But what I found was this: configured almost exactly like their legacy setup. 2.They managed access using manually configured Security Groups and Network ACLs — trying to mimic their old firewall rules. 3.Scalin…  ( 4 min )

Solana and Ethereum are two of the most popular blockchains in the world. But if you look under the hood, you’ll notice they speak different “languages.” Ethereum uses Solidity, while Solana uses Rust. So… what’s the difference? And why does it matter? Let’s break it down in plain English. Think of Solidity and Rust like languages people use to build apps — just like websites are built with HTML or JavaScript. Solidity was created specifically for blockchains — especially Ethereum. It’s simple, beginner-friendly, and looks a bit like JavaScript. Rust is more like the serious, high-performance cousin. It’s used to build powerful software like games, browsers, and now — Solana. One of the biggest problems in crypto? Bugs and hacks. Solidity, while easier to use, has been behind many major De…  ( 4 min )

What is a Laravel Observer? Observers in Laravel are used to listen for specific events on Eloquent models, such as creating, updating, and deleting records. The main advantage of using them is the ability to delegate the data handling logic to a dedicated class, keeping controllers and models leaner. Imagine you need to perform an action every time a user is created. Instead of writing that logic directly in the controller or the model, you can use an Observer to ensure that the logic is isolated and easier to test. Creating an Observer in Laravel is very simple. Let's take a look at a basic example of an Observer for a User model: php artisan make:observer UserObserver --model=User Open the App\Providers\EventServiceProvider file and register the observer: public function boot() { …  ( 4 min )

I'm thinking about starting a podcast with @blumen where we interview a bunch of somewhat successful / living-their-livelihoods-off-of-music people we went to music school with, and see where they are today. Basically Celebrity Catch Up: Life After I Did That Thing but without the Celebrity and without The Thing. 😬 Typing it out now makes it seem like a pretty bad idea, but I think it could be good information gathering for anyone considering music school or working in music. Plus, it would be amusing for our little cohort of music school grads and a fun way for us to reconnect with some folks. According to music-colleges.com (lol), SUNY Fredonia's music program ranks at #276 (out of 1451 schools they evaluated, so technically in the 20%!!). I imagine a podcast like this about Julliard grads would be much more successful, but those people probably wouldn't have good advice or relatable stories for real, non-prodigious but competent musicians. So far our initial brainstorm has us landing around: 30-45 min max Asking people about: What they studied How much schooling they ended up getting Their most memorable Fredonia experience What they do now Career highlights Career lows How much money they currently make (from music) What their advice would be for anyone pursuing their current career, or the program they studied in school Thoughts?  ( 3 min )

The Editor as a Storyteller: Crafting Meaning Through Cuts Film editing is far more than a technical exercise in arranging images; it is a profound act of storytelling. The editor shapes narrative, rhythm, emotion, and even truth by deciding what the audience sees—and when they see it. This power to construct meaning through selection and sequencing makes the editor an essential co-author of a film’s emotional and intellectual impact. At its core, editing transforms raw footage into a coherent and resonant experience. Through choices in duration, order, and juxtaposition, editors influence how characters are perceived, how themes develop, and how a story unfolds. The emotional arc of a scene—whether tranquil or intense—often hinges more on the cut than the shot itself. Editing allows a f…  ( 6 min )

Have you ever wondered how JavaScript functions can "remember" things even after they've finished running? That’s the magic of closures, and today we’ll break it down with a simple use case: building a custom counter function. We’ll touch on key concepts like function factories and state persistence to bring this idea home. Closures: For example, in our counter, a variable count is defined inside makeCounter(). The inner function (the actual counter) uses this variable. Thanks to the closure, the count is not lost when makeCounter() finishes, the counter function still remembers it. Function Factory: One Function, Many Counters Think of makeCounter() as a factory. Every time you call it, it gives you a brand new counter, like a fresh instance with its own private count. Each counter is completely independent. State That Sticks(State Persistence) The beauty of closures is state persistence. Since count is part of the closed-over scope, it keeps its value between function calls. That’s what allows the returned function to keep incrementing the same number, step by step. The key takeaway: even though makeCounter() is finished, the returned function still has access to everything defined inside it. That’s the closure in action, enabling encapsulation, memory, and a clean way to manage state without global variables. Closures aren’t just cool, they’re powerful. Once you understand them, you’ll start seeing them everywhere in JavaScript. And best of all, they make patterns like private counters, once complex, totally natural.  ( 3 min )

If you're building a product as a solo dev or part of a small team, you've probably struggled with design. You open Figma. You pick a font. Then a color palette. Then you browse some Dribbble shots. Then you go down a dark hole of animations, blur effects, neumorphism... and suddenly you've spent three hours tweaking gradients but your product still doesn't feel right. Here's the problem: you're thinking about design backwards. Design isn't about how your app looks. It's about what it lets people do and how easily they can do it. That's why I follow a dead simple rule: Design functionality first. Make it beautiful later. Design isn't about how something looks it's about what it lets people do. When you focus on visual details too early, you're decorating an idea that hasn't even proven its…  ( 5 min )

Hi DEV community! My name is Jo. I am a Digital Designer and Learning Technologist at the University of Leeds with a specialism in UX design and web accessibility. My coding journey started over lockdown when I completed a coding bootcamp with The Coders Guild, learning HTML, CSS, basic JavaScript, bootstrap, and Git. I will be honest, I don't need to use it every day for my career so I did forget some of what I've learnt since then but I have started to pick it back up again! My background is in graphic design so I hope to utilise my knowledge in this field to create more visually stunning web experiences. Currently with the support of my colleague, I help create bespoke web development projects that supplement the learning within our online course portfolio. For me personally, these projects are very basic (and partly supported by ChatGPT) because I am still learning... but I hope to change that! My goal is get to the point where I am much better and more confident in my skills at front-end web development and require less hand-holding. I also want to create diverse interactive experiences to hopefully foster genuine curiosity for the subject matter with our students and engage them with the learning material. Managers are more interested in boosting the reputation of the university, but the most important thing for me is to promote academia and make learning fun! Most of my posts will be misc stuff I've learnt and will probably be written with bad or inefficient code rather than being effective tutorials so please read with caution! Thank you for coming on this coding journey with me! If you'd like to connect, my LinkedIn profile is linked before (I no longer use any other social media platform anymore for my professional presence). I am in the process of coding my own website so be sure to keep a look out for this in due time! LinkedIn: https://www.linkedin.com/in/jolaw233/  ( 3 min )

“SQL is not about loops—it's about logic.

When working with Python and Bash scripts, logging output can become cumbersome, especially when you want to preserve the chronological order of the messages. The challenge you’re facing is that output from your Bash script is appearing in the log file before the output from your Python script due to buffering issues. This article will guide you through the best practices for ensuring that all outputs are recorded in the correct order, using file descriptors effectively. Understanding Output Buffering When Python writes output to a log file, it may use buffering, meaning it collects a certain amount of data before writing to the file. Similarly, Bash scripts can exhibit this behavior as well. When subprocesses are called within Python, outputs can arrive in an unpredictable sequence, there…  ( 5 min )

Back in 2022, my team and I were working on a service which was printing a fairly sizeable amount of logs from a distributed cluster of 20+ hosts: about 2-3 million log messages per hour in total. We were using Graylog, and querying those logs for an hour was taking no more than 1-3 seconds, so it was pretty quick. Infra people hated Graylog though, since it required some annoying maintenance from them, and so at some point the decision was made to switch to Splunk instead. And when Splunk was finally rolled out, I had to find out that it was incredibly, ridiculously slow. Honestly, looking at it, I don't quite understand how they are even selling it. If you've used Splunk, you might know that it has two modes: “Smart” and “Fast”. In “Smart” mode, the same query for an hour of logs was tak…  ( 4 min )

I've just released git-gpt-commit v0.9.0 — a Git extension that uses OpenAI's GPT models to automatically generate commit messages via the git gpt commit command. The default model has been upgraded to OpenAI’s GPT-4o. blazing-fast response speed (about twice as fast as GPT-4.1), allowing it to generate commit messages in an instant. very cost-efficient, at half the price of GPT-4-turbo. Previously, only English was supported. Now, with: git gpt lang You can choose from 12 languages for your commit messages: Previously, there was no option to add prefixes to your commits. Now, with: git gpt prefix You can toggle the inclusion of commit prefixes like feat:, fix:, or refactor:. Previously, you had to write your API key in a .env file in your project directory. Now, with: git gpt open-api-key You can now safely add and manage your OpenAI API key directly from the CLI. .env method is still supported as well. git gpt config You can now view all your current settings at once. Once installed, start by registering your OpenAI API key using the command above. Then, just stage your changes with git add, and run: git gpt commit The tool will analyze the staged changes, send them to the GPT model, and generate a context-aware commit message. You’ll need an OpenAI API key. npm install -g @laststance/git-gpt-commit While IDEs like VSCode and Cursor offer AI-assisted commit message generation, I couldn’t find a CLI tool that does the same — and that’s where I spend most of my time working with Git. Most of the features I personally wanted are now implemented, so I’m pretty happy with this release. Links: GitHub｜npm  ( 4 min )

In this problem, you're given a matrix of integers where each row and each column is sorted in ascending order. The goal is to find the index of the row that contains a specific target value. If the target value is not found in the matrix, return None. This is a common matrix problem that can be solved efficiently by taking advantage of the sorted structure. Instead of checking each cell (which would take O(n × m) time), you can reduce the complexity to O(n + m), where n is the number of rows and m is the number of columns. We make use of the matrix's properties—namely that values increase as we move right and down, and decrease as we move left and up. Start from the top-right corner of the matrix. Use a loop to traverse the matrix: If the current value equals the target, return the current row index. If the current value is greater than the target, move left. If the current value is less than the target, move down. If the loop completes without finding the target, return None. def find_row_with_target(matrix, target): if not matrix or not matrix[0]: return None # Matrix is empty n = len(matrix) # Number of rows m = len(matrix[0]) # Number of columns # Start at the top-right corner row, col = 0, m - 1 while row = 0: if matrix[row][col] == target: return row # Target found elif matrix[row][col] > target: col -= 1 # Move left else: row += 1 # Move down return None # Target not found matrix = [ [1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12] ] print(find_row_with_target(matrix, 7)) # Output: 1 print(find_row_with_target(matrix, 13)) # Output: None This solution demonstrates how understanding data structure properties can lead to more efficient algorithms. Instead of brute-force search, a directional approach through the matrix takes full advantage of the sorted nature, resulting in a linear time complexity relative to the dimensions of the matrix.  ( 4 min )

“When sub-second dashboards matter, pre-aggregation is your best friend — and materialized views are the weapon of choice.” In modern SQL-based systems, developers need fast, repeatable reporting queries.

Hey folks 👋 Over the past few months, I’ve been curating a large collection of interesting and useful GitHub repositories — projects that show up on Hacker News, Reddit, Twitter, or deep in GitHub itself. I’ve finally compiled over 7,000 repositories into a single browsable database. 🌐 Check it out here: The Internet Cafe It’s organized in a Notion-style format, categorized and searchable. I'm planning to keep updating and improving it over time, possibly adding filters, tags, and maybe an API if there's demand. 🧠 Why I built it: I wanted a personal archive of inspiring open-source projects. Hacker News has gems that disappear after a day. I figured others might benefit from the same archive. 📣 I’d love to hear your feedback — whether it’s about the format, usefulness, or features you'd like to see added. Let me know what you think — and feel free to share it if you think others might find it useful. Cheers!  ( 3 min )

Slow queries can quietly erode performance, which frustrates users and strains your system. Fortunately, MySQL offers EXPLAIN, a diagnostic tool that reveals how your queries execute. Think of it as a window into your database engine’s decision-making process. With EXPLAIN, you can figure out exactly why a query is underperforming. Maybe it’s looking at too many rows, ignoring indexes, or struggling with joins. This understanding is key for developers and database administrators who are aiming to optimize performance. To use EXPLAIN, simply place it before your query. It works with SELECT, INSERT, UPDATE, or DELETE statements. For instance: EXPLAIN SELECT name, email FROM customers WHERE age > 30; This will return the query execution plan in table format. +----+-------------+-----------+…  ( 8 min )

Introduction When working with Jest in a TypeScript environment, particularly with mocked functions, you may encounter issues where one test affects another. This problem often arises when mocking is not properly reset, leading to test interference. In this article, we’ll explore why this side effect occurs and provide you with effective solutions, especially in your example involving test cases for the loginPagePresenter. Understanding the Side Effect In your case, the issue stems from the way Jest mocks the apiGateway.post function.

Jest mocks maintain their state across tests unless specified otherwise. This can lead to unexpected results, especially in scen…  ( 4 min )

The common approach to using sprite sheets involves applying CSS classes with pre-calculated coordinates to control the positioning within the sheet. This typically relies on background-image, which does not natively support features like alt text or lazy loading that come built-in with elements. Additionally, using can improve accessibility and semantics depending on how the image is used. This approach builds upon an article on css-tricks, and expands it by introducing scaling of the individual sprites. Skip to Codepen Demo object-fit: none and object-position: x y allow us to select specific areas of an image which is the basis of this idea. The object-position values need to be pre-calculated, just like in the class-based approach. This could be stored as an object literal…  ( 5 min )

For a SaaS (Software as a Service) product, choosing between MySQL and MongoDB depends heavily on the type of data, scalability needs, and how the app works. Use Case Recommendation Traditional SaaS (multi-tenant, structured data, relational) ✅ MySQL Flexible, unstructured, dynamic data (e.g., user-generated content, document-heavy) ✅ MongoDB Feature MySQL (Relational) MongoDB (NoSQL Document) Data Structure Tables, Rows, Foreign Keys (SQL) JSON-like Documents (BSON) Schema Fixed schema (strong structure) Schema-less (flexible) Joins & Relationships Native support Complex joins are harder Transactions Strong ACID support ACID (limited or requires special setup) Scalability Vertical + Read replicas Easily horizontally scalable Performance Great for complex queries, joins Fast for large, flexible datasets Multi-Tenancy Support Very strong (tenant per row, schema, DB) Requires thoughtful design MySQL: SaaS with complex relational data (users, roles, payments, subscriptions). Requires data integrity and transactions (e.g., financial systems). Example: B2B CRM, ERP, Invoicing software. Strong multi-tenant support using shared schema with tenant_id. MongoDB: SaaS with highly dynamic or nested data, like CMS or analytics dashboards. You don’t rely heavily on relationships or joins. You need to store flexible documents per user. Faster iterations and schema evolution. SaaS Type Best DB Project Management Tool (tasks, users, teams) ✅ MySQL CMS/Blog Platform ✅ MongoDB Analytics or IoT Dashboard ✅ MongoDB Accounting / Billing SaaS ✅ MySQL Chat/Messaging SaaS ✅ MongoDB (with Redis/Cache) Some large SaaS companies use both: MySQL for core user/accounts/transactions. MongoDB or ElasticSearch for logs, analytics, unstructured content. If you are: Building a structured SaaS with users, payments, plans, etc. → go with MySQL Building a dynamic content-based platform or analytics service → go with MongoDB  ( 3 min )

As an IAM SaaS company, our work often remains in the shadows—until something goes wrong. Today, I want to shed light on how we handle security at the very first layer all IAM systems have: the login page. Specifically, I’ll walk you through an incident we managed at Cloud-IAM, where we provide a managed Keycloak solution, and share some insights on securing authentication systems against evolving enumeration attack threats. Many of our clients are tech enthusiasts and small companies that want to avoid the complexity of configuring and maintaining Keycloak. Our larger clients, on the other hand, demand resilience. However, resilience is often measured in terms of Monthly Active Users (MAUs), without fully considering the exposure of their service. For example, take two hypothetical compa…  ( 6 min )

When working with JWT authentication in C#, you might encounter a common issue: the token signature validation fails due to a missing 'kid' (Key ID) in the header. This issue often surfaces when using the HS256 algorithm without a kid component, particularly when your token is validated against a set of keys that do not match. Understanding JWT Tokens and Signature Validation JWT (JSON Web Token) is a widely used token format for secure communication between parties. A JWT typically consists of three parts: header, payload, and signature. The header contains information about how the token is signed, including its algorithm and, optionally, a 'kid' if multiple signing keys are involved. In situations where the 'kid' is missing, the application may not be able to match the signing key prope…  ( 4 min )

“Europe’s new space telescope will create a 3D map of the cosmos to explore the effects of dark energy.”– Korey Haynes In one of my earlier blogs, we spoke about the James Webb Space Telescope and how it is changing our understanding of the universe.

Elm is renowned for its commitment to reliability and predictability in web applications. One of the key design decisions behind Elm’s success is its strict enforcement of managed side effects. Unlike many other languages where developers can introduce side effects at will, Elm mandates that all interactions with the outside world be handled only through its controlled mechanisms. This deliberate choice helps maintain purity, consistency, and overall code health. In this post, we’ll explore: What side effects are and why arbitrary side effects can be problematic. The advantages of Elm’s enforced, managed approach. How Elm implements this design with Commands (Cmd) and Subscriptions (Sub). Real-world scenarios that benefit from this disciplined strategy.

“An icy visitor flames out in dramatic fashion”– Sean Walker A comet is a small icy object that orbits the Sun. It’s made of dust, rock, and frozen gases (like water ice, carbon dioxide, and more). I’m sure that everyone’s familiar with this definition of a comet, but today we’re not talking about comets in general but a specific one — ATLAS! Comet ATLAS or C/2024 G3 was named after ATLAS- Asteroid Terrestrial-impact Last Alert System, which was the first to discover it. Comet ATLAS was a 19th-magnitude object. To explain, the magnitude of an object measures its brightness. The brighter the object the lower the number. The comet is also described as having a diffuse coma and a short tail. A coma is a cloud of gas and dust that forms around the nucleus of a comet upon receiving heat from th…  ( 4 min )

In Java, file reading and writing can be done efficiently using buffered streams, readers, and writers. Here's a short explanation with examples: 1. Buffered File Reading (Using BufferedReader) Buffers data for efficient reading (instead of byte-by-byte). import java.io.BufferedReader; import java.io.FileReader; import java.io.IOException; public class ReadFile { public static void main(String[] args) { try (BufferedReader reader = new BufferedReader(new FileReader("file.txt"))) { String line; while ((line = reader.readLine()) != null) { // Reads line-by-line System.out.println(line); } } catch (IOException e) { e.printStackTrace(); } } } 2. Buffered File Writing (Using BufferedWriter) Buffers data for efficient writing. import java.io.BufferedWriter; import java.io.FileWriter; import java.io.IOException; public class WriteFile { public static void main(String[] args) { try (BufferedWriter writer = new BufferedWriter(new FileWriter("output.txt"))) { writer.write("Hello, Java!"); writer.newLine(); // Adds a newline } catch (IOException e) { e.printStackTrace(); } } } 3. Key Classes Class Purpose FileReader / FileWriter Reads/Writes characters (text files). BufferedReader / BufferedWriter Wraps readers/writers for buffered I/O. FileInputStream / FileOutputStream Reads/Writes bytes (binary files). Scanner Alternative for reading text (e.g., new Scanner(new File("file.txt"))). 4. Try-with-Resources Automatically closes files (no need for finally blocks). Used in the examples above (try (BufferedReader ...)). When to Use? Use BufferedReader/BufferedWriter for text files. Use FileInputStream/FileOutputStream for binary files (images, etc.). Use Scanner for parsing structured text. Let me know if you'd like a deeper explanation! 🚀  ( 3 min )

✅ Understanding the Goal You're being asked to implement a function called deepEqual(valueA, valueB) that checks if two values (which can be primitives, objects, or arrays) are deeply equal. The keyword here is deep, this means we can’t just check equality on the surface (like ===), especially for things like objects and arrays. We need to go into nested levels and check if all elements or properties match recursively. 🧠 Think Like This, Before you jump into code, ask yourself questions like: -> What types of values can valueA and valueB be? -> How do I handle primitive types vs arrays vs objects? -> What does it mean for arrays or objects to be “equal”? -> Should I use recursion? 🤔Design Your Thinking Strategy: Base case: If a === b, return true. Type check: If types differ, return false. If both are arrays: Check length. Recursively compare each element. If both are objects (but not arrays): Compare keys. Recursively compare each corresponding value. Otherwise: return false. 🔁 Why Recursion? Why Loops Alone Aren’t Enough? A simple for loop works great when you're comparing flat structures, like two arrays of numbers. But when the data can go many levels deep , arrays inside objects inside arrays, etc. you’d need: a loop inside a loop inside a loop... 😵 or a smarter approach that can handle any depth That’s Where Recursion Shines. Recursion is perfect for tree-like or nested structures, because you can say: “If the current level is an array or object, go deeper and run the same logic again.” So your function ends up being clean and adaptable to any depth. ⚡️Implementation of the deepEqual function using recursion: With a clear understanding of recursion and careful handling of data types, you now have a robust deepEqual function that can accurately compare even the most nested structures, a must-have tool in any JavaScript developer's toolkit.  ( 3 min )

At first glance, an ID might seem like the most boring part of your application. It's just a unique identifier, right? But if you're building systems that scale - across regions, across teams, across microservices - your ID generation strategy can be the silent hero or the hidden landmine. And that’s exactly why companies like Netflix, Twitter, Stripe, and Shopify have ditched traditional auto-incrementing IDs in favor of UUIDs and Snowflake-like systems. Let’s explore why UUIDs are not just random gibberish, but a critical architectural decision in high-scale systems - and what lessons we can steal from the giants. Auto-incrementing integers are deceptively simple and convenient. They work great when: You have a single database. You can guarantee a single source of truth. You're not worri…  ( 5 min )

When reading discussions about C++ variable definitions and their associated rules, it’s essential to understand the distinctions between variable definition, initialization, and assignment. Each concept plays a crucial role in how variables behave within C++ code, and knowing these differences can significantly enhance your programming efficiency. Let's delve deeper into variables in C++ and clarify these terms with examples. Understanding Variable Definition In C++, variable definition is the process of declaring a variable to let the compiler know the variable’s type and its name. For instance: int x; // Variable definition Here, int x; tells the compiler to reserve space in memory for an integer variable named x. However, at this point, x does not hold any value; it’s simply defined. …  ( 5 min )

Google is testing a new “Desktop View” mode in Android — and it’s more than just screen mirroring. We’re talking about taskbars, resizable windows, mouse support, and full-on multitasking. Basically, a PC layout powered by your phone. If this rolls out, it could mean you won’t need a Samsung device to get that DeX-style desktop experience. Hidden taskbar (like Windows or ChromeOS) Drag-and-drop between apps Resizable, windowed apps Smooth support for external monitors Mouse + keyboard ready It’s currently tucked away in Android beta builds, but signs suggest Google is moving fast with this. Samsung DeX gave us a glimpse of mobile desktop computing. But now Google is building something native — possibly for all Android phones. That means more freedom for users, especially those who want to work on the go with just a phone and a screen. This could shift how we think about smartphones in workspaces.

Imagine you're trying to teach a child how to recognize fruits. You show them dozens of apples, bananas, and oranges, telling them the name of each fruit. Over time, the child learns to distinguish between them, even when they see new fruits for the first time. This, in a way, is what Machine Learning (ML) is all about—teaching machines to learn from data and make decisions or predictions without being explicitly programmed. 🧠 So, What Is Machine Learning? At its core, Machine Learning is the art and science of solving problems by learning from data. We start with a problem, gather data related to it, and then use algorithms to build a statistical model that can make sense of new, unseen data. But ML isn’t one-size-fits-all.

Introduction Traditional perimeter-based security models are no longer adequate to protect against today's sophisticated and evolving cyber threats. The Zero Trust Security Model offers a fundamental shift: trust no one—inside or outside the network—by default. Zero Trust enforces the principle of least privilege access, evaluating every access request individually. Unlike the traditional "castle-and-moat" model, Zero Trust assumes perpetual network exposure and ensures granular control over who can access what. Remote Work Expansion: Employees now access corporate resources from multiple devices and locations, dissolving traditional boundaries. Cloud Adoption: With workloads moving to the cloud, network-based access control is ineffective. Internal Threats: Trusting internal users witho…  ( 4 min )

In the vast world of computer science, while the foundations and principles of algorithms remain consistent, the ways we approach, implement, and analyze them continue to evolve. Today, we’ll delve into a distinct implementation of the insertion sort algorithm and an innovative tool that simplifies its analysis, both brought to the fore by Fernando Pelliccioni. The provided algorithm, while rooted in the classic insertion sort paradigm, offers a twist — working its magic backward: `function insertion_sort_backward(f, l, r) { } function linear_insert_backward(c, l, r) { var s = sequence(array_descending(), "s", lt); print(s); Understanding an algorithm is one thing; seeing it in action is another. Fernando Pelliccioni introduces an insightful GUI tool for this very purpose: componentsprogramming.com/algorithms. This interactive platform not only animates the algorithm’s execution but also serves insights into memory sequences, variables, stack calls, and various operation statistics. A glimpse into the potential data output: n: 10 (Note: The above metrics are illustrative and may not reflect the actual values for specific runs.) While the foundational algorithms might be familiar territory, it’s the nuanced implementations and tools for deeper understanding that elevate our coding journeys. Fernando Pelliccioni’s distinct implementation of the insertion sort and the accompanying analysis tool stand as testaments to innovation in the world of algorithms. Whether you’re a programming veteran or a newcomer, the landscape of algorithms always promises fresh terrains to explore.  ( 4 min )

Introduction In C++, the distinction between friend functions and public member functions is crucial for encapsulation and access control within classes. Both have unique roles when it comes to interacting with class data, yet they serve different purposes and use cases. In this article, we'll explore the differences between friend functions and public functions, clarifying why you might opt for one over the other. Understanding Access Control in C++ Classes C++ employs a strict access control mechanism to ensure data encapsulation. This mechanism encompasses three main categories: public, private, and protected. Public members can be accessed from outside the class, while private members are restricted to the class itself. Protected members, on the other hand, are accessible in derived cl…  ( 5 min )

Introduction This report aims to comprehensively analyze the origins, development history, and controversial position of the Comic Sans font in the design community and among the general public. Comic Sans, as a widely used but controversial font, has become a cultural phenomenon since its release in 1994, sparking extensive discussions about font design, appropriate usage contexts, and readability. Comic Sans was designed by Vincent Connare in 1994 for Microsoft, originally intended to provide a more stylistically appropriate font choice for cartoon character speech bubbles in Microsoft Bob software. Design inspiration came from comic book lettering styles, particularly "The Dark Knight Returns" (lettered by John Costanza) and "Watchmen" (lettered by Dave Gibbons).

Dia 2 - Neurointerfaces — Como nosso cérebro enxerga o Frontend “Don't make me think.” — Steve Krug Essa frase virou um clássico do design de interfaces. E ela tem base neurocientífica: nosso cérebro evita ao máximo o esforço cognitivo desnecessário. Segundo a Teoria do Processamento Dual (Kahneman, 2011), o cérebro humano opera com dois sistemas: Sistema 1: rápido, automático, intuitivo. Sistema 2: lento, deliberado, requer esforço. Sempre que possível, o cérebro usa o Sistema 1 — e só ativa o 2 se for realmente necessário. Isso significa que interfaces que exigem leitura, análise ou adivinhação ativam o sistema mais lento — e geram frustração. Ícones sem legenda (usuário precisa adivinhar) Menus escondidos (hambúrguer, submenus profundos) Mudanças de padrão (ex: botão de "enviar" que parece um ícone) Elementos previsíveis e familiares Legendas claras Hierarquia visual forte Espaço em branco bem utilizado Estudos de eye-tracking (rastreio ocular) mostram que usuários criam um padrão de leitura em F na tela. Isso significa que eles escaneiam de cima para baixo e da esquerda para a direita — e ignoram o resto. Kahneman, D. (2011). Thinking, Fast and Slow. Krug, S. (2014). Don't Make Me Think, Revisited: A Common Sense Approach to Web Usability. Nielsen Norman Group (2006). F-Shaped Pattern For Reading Web Content. Essas obras explicam por que o design intuitivo funciona melhor: ele não força o cérebro a sair do “modo automático”. Reduza a necessidade de pensar. Use padrões comuns da web. Priorize clareza sobre criatividade. Não reinvente botões sem motivo. Dê pistas visuais. Ícones com texto, hierarquia, espaçamento. Teste com usuários reais. Se alguém hesita antes de clicar, sua interface não está clara o suficiente. Criar uma interface clara é um ato de empatia: você está poupando energia mental do seu usuário. Se ele entender o que fazer sem precisar pensar, você venceu. Qual interface você achou mais confusa recentemente? Comenta aqui e vamos analisar no próximo post da série! 👇  ( 4 min )

What if your design system didn't need to ship components in a component library? From an engineering standpoint, most of a design system's maintenance overhead is creating and shipping components for a specific framework coupled to a styling system of some kind. I've been asking the same thing on Medium. And then built a POC to see if it would work and made it available in Github. If using AI agents, component libraries break free of framework and style constraints by generating components at build time from prompts and generator functions. They're still driven by design through tokens and themes, but without prebuilt components. It gets even better when using RAG for distribution and documentation, eliminating tools like Storybook in favor of on-demand generation by AI agents using the system itself, not a collection of stories or API documentation.  ( 3 min )

Hey all, We recently started working on an API Client - Voiden - and wanted to share it here to get your thoughts and feedback. Over the past few years, we found ourselves managing way too many tools just to work with APIs: one for api specs, another for docs, a third for tests, etc etc. Eventually it starts to feel more like a performance than actual work. So we built Voiden: A git-native, extensible, and lightweight client that brings everything—specs, docs, tests, mocks—into one place. No bloat, no lock-in, no "platform overhead." Just structured API workflows that don’t fight your tools or your team. A few things we care about: -Reusability and composability : APIs as building blocks, not silos. -Structure over scatter : everything lives together in one workspace. -No sign-in required : you can use it without creating an account. Free and open — we are building this with the community in mind. Just to be clear: The goal is NOT to replace OpenAPI, but to provide a layer around existing specs that feels coherent, hackable, and friendly to real-world dev workflows. You can check it out here: https://voiden.md/ And if you have feedback, suggestions, or just want to follow along: https://github.com/VoidenHQ/feedback We are still early, but would love to hear what you think—what you like, what is missing. Appreciate any time you take to try it out. Nikolas  ( 3 min )

Introduction Can we store polymorphic objects by value in C++ STL containers? This topic often arises among C++ developers, particularly with the challenges posed by object slicing when dealing with base and derived classes. The crux of the issue lies in the behavior of STL containers and how they handle objects. In C++, when we store derived class instances in a container that holds base class objects by value, object slicing occurs, which results in the loss of the derived class-specific behaviour. This article aims to explore this concept specifically within the context of C++11 and later revisions, dissecting the challenges and potential approaches. Understanding the Slicing Problem When you store a derived class object in a container designed to hold objects of its base class by value…  ( 5 min )

Building resilient, production-grade workflows means preparing for the unexpected—from task stalls to external service outages. While task-level timeouts catch issues in isolated steps, workflow-level resilience settings act as a safety net for your entire orchestration. They ensure your system behaves predictably under stress and provides a graceful fallback when things go wrong. In this post, we’ll explore two key features in Orkes Conductor that help you build robust workflows: Workflow Timeouts Failure Workflows (a.k.a. Compensation flows) A workflow timeout defines how long a workflow is allowed to run before it's forcibly marked as timed out. This is crucial when your business logic needs to meet service-level agreements (SLAs) or avoid workflows stalling indefinitely. Workflow timeo…  ( 6 min )

Imagining AI Companions as Conversationalists in 2025 The evolution of artificial intelligence is impressive. Sitting here in 2025, AI chat companions are capable of conversation in ways we never thought would be possible. No longer are these digital companions simple conversationalists who follow a script; now, they can communicate with understanding of context and emotion through any form of dialogue—academic or sexual. Consider yesterday's scenario. Once upon a time, chat functionality existed in simple programs that fell apart if the user strayed even slightly from the predetermined prompt. But that's not the case in 2025. Today's counterparts exist in a world far removed from yesterday's failed experiments. With context-cued language models trained on billions of conversations, thes…  ( 6 min )

🔐 Temporary credentials in AWS are powerful—but also widely misunderstood. They allow developers and systems to access AWS resources without relying on long-lived access keys. But just because they expire doesn’t mean they’re safe by default. In this post, I break down: ✅ When and why to use temporary credentials 🧱 Where things go wrong (over-permissive roles, lazy session durations…) 🔒 Best practices for keeping temp creds secure 🧠 Advanced use cases like federation and IAM Roles Anywhere I’ve seen real-world setups where: Temp credentials lasted 12 hours Were used with AdministratorAccess In CI/CD pipelines with no monitoring That defeats the whole point of ephemeral access. Should Be Doing 🔸 Use least privilege roles Scope your roles tightly and use IAM condition keys like aws:SourceIp. 🔸 Shorten session durations 15–30 minutes is more than enough for most automation tasks. 🔸 Log STS usage with CloudTrail Every AssumeRole or GetSessionToken should be traceable and alertable. 🔸 Require MFA where appropriate Especially for sensitive role assumptions—break-glass or prod access. 🔸 Automate responsibly Don’t reuse temporary creds or store them insecurely in config files. Use the SDKs properly. For non-AWS workloads (like on-prem apps), IAM Roles Anywhere lets you issue short-lived AWS credentials using signed certificates. It's a powerful addition for hybrid setups, but comes with its own set of guardrails. The original article goes deeper into: Federation setups with Okta or AzureAD Example real-world misuses (and fixes) Credential rotation strategies 👉 Read the full guide here Let me know: How is your team managing AWS access today?

When diving into the Swift language, especially for those new to the community, understanding how the Swift compiler treats opaque type declarations can be confusing. In your example, you're encountering a common scenario that many developers face when dealing with opaque types in Swift. Let's clarify this by breaking down your code and explaining why the behavior you're seeing is occurring. Understanding Opaque Types in Swift Swift's opaque types, introduced with the some keyword, allow developers to specify that a function will return a value conforming to a specific protocol without revealing its exact type. This is particularly useful for abstracting away implementation details while still adhering to protocols. In your code: protocol Animal {} class Dog: Animal {} func getMeADog() -…  ( 5 min )

At its core, FTP is a standard network protocol used to transfer files between a client and a remote server. Introduced in the early days of the internet, it was originally designed to simplify data sharing across ARPANET. Today, its primary use remains the same—allowing users to upload, download, and manage files between devices and systems across networks. While web browsers offer limited FTP support, professionals often turn to dedicated tools like FileZilla and Cyberduck to handle more advanced workflows. An FTP session typically initiates two connections: Control Channel: Handles command exchange and session setup. Data Channel: Transfers the actual file content. This dual-channel approach allows FTP to streamline complex file operations, enabling simultaneous uploads and downloads wi…  ( 4 min )

Beyond Small Talk: How AI Chatbots Surpassed the Uncanny Valley by 2025 Remember when chatting with AI was like talking to a glorified calculator with some sarcastic punchlines? Such memories are quickly becoming a thing of the past, though. By 2025, chat-based communication with AI has reached such great heights that it's practically comparable to human communication in certain unexpected realms. The shift from having simple first-chatbots to playing with AI to now conversing with it fully is one of the most impressive developments in contemporary computing.

The Mechanics of Humanization But how is this happening? Are all these people really transferring from talking to humans to talking to machines? What does the language model operate behind these AIs? In 2025, there is no ambiguity between talking and chat bots. It's framed mostly by instruction and subsequently, output. Of course, the ability for AI to talk like a human wasn't developed overnight either. Over the years, developments in large language processing models have created systems that operate on trillions of parameters - whereas previous iterations operated on mere billions. This difference of magnitude means that AI can better understand context, remember previous messages and conversations, and stay on task within one stream of consciousness across lengthier periods.

Structured Query Language (SQL) is an essential tool for working with databases, but even seasoned developers sometimes make mistakes that can lead to slow queries, inaccurate data, and inefficient systems. When summarizing data, the GROUP BY clause organizes information into meaningful groups. However, misusing GROUP BY can lead to incorrect results—sometimes without obvious errors. A database tracks employee salaries per department. Someone writes: sql To summarize salaries by department, the query should be: sql sql Only group necessary columns—non-grouped columns need aggregate functions. Use HAVING instead of WHERE for filtering grouped results: sql During testing, SELECT * is quick and handy. But in production? It slows queries, overloads networks, and makes applications harder to maintain. sql sql Explicitly specify needed columns instead of SELECT *. Use LIMIT for large queries: sql sql sql Indexes speed up data retrieval, but poorly designed indexes can slow down updates, inserts, and deletes. sql A better strategy: sql Index columns frequently used in WHERE clauses. Avoid over-indexing, which slows write operations. Use EXPLAIN or ANALYZE to check query performance: sql Use composite indexes only when queries filter by multiple columns: sql NULL values represent missing information, and if not handled correctly, they can cause errors or misleading results. This query calculates average salaries: sql Ensure NULLs are accounted for: sql sql Use IS NULL and IS NOT NULL to prevent logic errors. Replace NULLs using COALESCE() or IFNULL(): sql Validate NULL handling in reports to avoid misleading calculations. SQL mistakes can affect speed, accuracy, and system stability. But with the right practices, you can write efficient, optimized queries that scale well. GROUP BY must include all non-aggregated columns to avoid incorrect grouping. Never use SELECT * in production—fetch only required data. Index smartly, targeting commonly searched fields. Handle NULLs carefully, ensuring accurate calculations.  ( 4 min )

If you're building coding agents or automated developer workflows, you'll quickly discover the challenge of finding a robust, non-interactive CLI tool for code generation and modification. While human-in-the-loop coding (where a developer guides the AI) is still the gold standard for complex software, there's a growing need for tools that can operate fully autonomously—especially for simple, repetitive tasks or as part of larger agentic systems. I'm working on building an AI agent for creating playable ads—essentially mini games that can be used as interactive advertisements.

When I first thought about switching from Windows to Linux, the main reason was simple — I want to control my computer. ⚙️ I love to automate everything One of the main reasons I chose Linux is the ability to automate everything. Every update, every new package — I decide what and how to install. This isn’t tied to forced downloads like in Windows. This is my freedom. 🌍 A world of options Linux gives you a huge variety of distributions, each suited to different needs. It’s like a builder where you choose what you need: I started with Ubuntu, because it’s stable, user-friendly, and has good documentation. But now I’m getting more interested in Arch and Fedora. I’ve realized that in Linux, it’s easy to switch between distributions, migrate between them, and adapt the system to your needs. 💻 Tech and CTF My passion for CTF and cybersecurity gave me even more reasons to switch to Linux. This system provides me with the tools to work with security, set up virtual machines, create test environments, and perform various attacks. You can’t achieve that in Windows, not to the same extent. Linux is a system for people who not only want to use technology but also understand it from the inside. For me, it’s not just an operating system, it’s a tool for growth and self-expression. 🌟 My freedom After switching to Linux, I felt that I was finally in control of my system. It’s not just an OS, it’s an environment that allows me to build, optimize, and use my computer the way I need. 🚀 Final thoughts If you’re tired of your computer not being yours, try Linux. A system where you decide how everything works. Where you can customize everything, automate it, and learn. It doesn’t matter if you’re a beginner or an experienced user — Linux has something for everyone.

Summary WhatsApp imposes a 24-hour customer-service window during which you can send any message; outside of it, only template messages (unformatted) are allowed. Goalmatic.io needs to let users send richly formatted content (articles, poems, etc.), so we built a two-step workaround: Template Send: Strip formatting and send via a WhatsApp template. On-Click Upgrade: Include a “Get Formatted Text” button in the template. When the user clicks, the 24-hour window reopens, allowing us to send the original, fully formatted message. Below is an end-to-end example in Node.js using the WhatsApp Cloud API. WhatsApp’s customer-service window rules mean: Within 24 hours of a user message, you can send any content (text, media, formatted).

We will focus specifically on how to ensure that errors thrown from your view model can be gracefully handled at the view level. Understanding the Issue In Swift applications, especially those using SwiftUI, it can sometimes occur that errors that are thrown from a view model do not propagate to the view layer. This can lead to confusion as you may not see the expected error messages in your user interface. In your case, while the error logging from the network layer indicates that an error is being produced, the error isn't…  ( 5 min )

When developing web applications, storing data in the browser is essential for maintaining user sessions, saving preferences, and improving performance. Three common methods for client-side storage are Local Storage, Session Storage, and Cookies. While they serve similar purposes, they differ in data persistence, size limits, and accessibility. This article will explore the differences, advantages, and best use cases for each storage method. Local Storage is a browser-based storage mechanism that allows web applications to store key-value data persistently on the user’s device. The stored data does not expire and remains available even after users close and reopen the browser. ✔️ Persistent Data — Data is stored permanently until manually deleted // Storing data in Local Storage localStora…  ( 5 min )

Hey Devs! 👋 Yeah, I know… it’s been a while 😅 LearningTrackApp (name still under construction 😅) So this new app I’m building is a platform made for NGOs — specifically the ones that teach underprivileged kids. The idea is to help them keep track of their students’ progress, batch sessions, timings, names — basically everything important in one place. It’s simple, but I think it’s gonna be really useful. The app has a few different roles to keep everything organized: Super Admin – can access and manage all the NGOs. Admin – manages just their own NGO. Supervisor – the on-site person ensuring sessions are running smoothly. Volunteers – the awesome people who teach the kids. Students – well, this one explains itself 😄 That’s pretty much what I wanted to share for now. I genuinely feel like this app can be something impactful, and I’m excited to build it step by step.

Writing clean SQL is about more than just correctness—it's about clarity. SQL comments help you communicate with others (or your future self) by adding context, notes, or temporarily disabling code. Let’s explore how to use comments effectively. Using Comments in SQL Two Main Types: Single-line -- Pull users created in the last week SELECT * FROM users WHERE created_at >= CURRENT_DATE - INTERVAL '7 days'; Multi-line /* Use this version for reporting Includes only verified accounts */ SELECT * FROM accounts WHERE verified = TRUE; Why and When to Comment Helpful When: Writing complex logic Sharing scripts with a team Disabling old queries during testing Avoid: Leaving sensitive info Explaining simple queries Letting comments go stale Different Engines, Different Capabilities MySQL: Supports versioned comments /*! */. PostgreSQL: COMMENT ON lets you label schema elements. SQLite: Keeps it basic and portable. SQL Server & Oracle: Great for documenting stored code and schema. FAQ How do I add comments in SQL? Use -- for quick notes or /* */ for multiple lines or blocks. Yes—wrap code in /* */ and it won’t run. Yes, both styles are widely supported with small engine-specific features. Only if they include secrets or mislead developers. Keep them clean and relevant. Conclusion SQL comments don’t take much effort but make a big difference.

Let’s walk through some practical tips and real Go examples to help you write cleaner and more idiomatic code. Don’t try to be clever. Clarity beats brevity every time. ❌ Bad: func f(u int) { fmt.Println(u) } ✅ Good: func printUserID(userID int) { fmt.Println(userID) } Use camelCase for variables and functions. Reserve abbreviations for widely recognized terms like id, url, db. One function = one responsibility. Break up logic when possible. ❌ Bad: func h…  ( 5 min )

In Python programming, it's common to define constants that are used throughout your code. These constants, stored in a file like constants.py, can help keep your code organized and make it easier to update settings or values in the future. However, when documenting functions that use these constants, developers often face the dilemma of whether to refer to the constants directly in the documentation or use their values instead. Why Use Constants in Python? Constants like PATH_DATASETS = "data/datasets/" and WIDTH = 416 serve as fixed values that can be reused across multiple functions in your program. This practice enhances code readability, maintainability, and minimizes the risk of introducing errors when changes are needed. The Problem with Documentation When you define a function that…  ( 5 min )

The Hook: Remember When Investing Meant Picking Stocks Based on Your Gut I still recall my initial portfolio-building effort. It was 2011. I purchased a few tech stocks because, you know, "tech is the future," right? I did my research by spending two hours on Reddit and a tip from a colleague who once read The Intelligent Investor. Of course, I lost money. Flash-forward to the present day, and we're in a whole different galaxy. You no longer need a finance degree or a Bloomberg terminal. You just need an app—driven by AI. Artificial intelligence is not only upending finance—it's changing the way portfolios are constructed, managed, and optimized.

One of the key challenges I have found with the built in Power Platform Pipelines is that it doesn't cover connections. The expectation is that the developer will deploy to production through a spn (as we don't want them to have access to edit production), but the new flows use the developers connections, wait what. The 2 benefits of ALM are: Cant access prod If they leave still works Well with this setup the developer still needs access to the prod data source, and if they leave it breaks. Fortunately there is a way, well actually 2. Matt Collins-Jones found the best way and documented it brilliantly at https://www.mattcollinsjones.co.uk/single-post/change-connections-during-deployments-power-platform-pipelines, I highly recommend reading it My way is a lot less graceful, but has the on…  ( 6 min )

What if I told you that building large, feature-packed mobile apps is no longer the smartest move? We're entering an era where micro-apps — small, self-contained, purpose-driven applications — are transforming how we build and scale mobile experiences. And if you're not exploring them yet, you're already behind. A micro-app is a lightweight, independent application designed to handle a specific task or feature. Think of it as a “microservice,” but for the frontend of mobile apps. They're typically: Built independently from the main app Focused on one specific use-case (e.g., payment, chat, onboarding) Easily deployable without affecting the entire app Written in a variety of frameworks or stacks Instead of one monolithic app that tries to do everything, you create multiple micro-…  ( 5 min )

👋 Hello Dev Community — From Guyana with Love! Hey everyone! I'm Nathaniel, a developer and computer science student from Guyana — a small country on the South American mainland. I’m passionate about writing clean code, building full-stack applications, and diving deep into topics like JWTs, web architecture, and system-level programming in C. But beyond that, I’m also deeply interested in how technology is growing (or struggling) in Guyana — from internet access to education to the startup scene. To share dev articles and tutorials, especially things I’ve learned or struggled with as a student and builder. To spotlight Guyana’s tech space, which I think deserves more global attention and internal discussion. To connect with other developers, both in the Caribbean and internationally, and learn from their stories as well. I’ve noticed there's not a lot of content on Dev.to about tech in Guyana, so I want to help change that. Whether you’re here for tutorials, dev opinions, or insights into building a tech career from a small country, I hope my posts can add value. Feel free to reach out, share your thoughts, or even suggest topics you'd like to see discussed.  ( 3 min )

In TypeScript, creating generic functions can significantly increase your code's reusability and type safety. One common requirement is to extract keys from a given type, ensuring that your functions handle different types effectively. In this article, we will focus on how to implement the get_keys() function, which retrieves the keys of a specified type T. Understanding the Requirement The get_keys() function is designed to return the keys of any given type T. This function will be helpful when you want to dynamically work with the properties of objects or interfaces defined in TypeScript, especially when you are dealing with complex data structures. By doing so, you can create a more dynamic and type-safe codebase. Why Use TypeScript's Generics? Generics in TypeScript allow you to …  ( 5 min )

I originally posted this post on my blog. I didn't pay for the most expensive hamburgers I've eaten. An ex-employer did. When I say "most expensive," I mean the same greasy $5 or $10-dollar hamburger from a food truck or a corner in a busy street. But they felt expensive because I ate them while working overnight. In a past job, when my team was lagging behind the self-imposed deadlines of sprints, higher-ups told us: "This sprint is behind schedule. What are you going to do? You're a self-managed team, so decide that by yourselves. But if I were you, I'd choose to work overtime to keep up." "You're a self-managed team" was their subtle way of telling us to work extra hours, without accepting any responsibility. We didn't have any say in what tasks to do and how. We were only a self-managed team when it came to choosing to work overtime. They didn't pay us for that extra time. They only bought us hamburgers. And, when someone raised their concerns about the quality of those hamburgers, they told us we should be grateful because other companies buy their employees nothing to eat. If you're told you're part of a self-managed team, read the fine print. Look for signs of real self-managed teams: Look at job descriptions. Connect with people already working there. Ask follow-up questions during interviews. Otherwise, they might expect you to work overtime without compensation or just buy you an hamburger.

When optimizing Angular applications for performance, developers often overlook a silent culprit: TypeScript enums. While enums improve code readability and type safety, they introduce unexpected overhead in your final JavaScript bundle. This can lead to larger file sizes, slower load times, and diminished performance, especially on mobile or low-bandwidth connections. In this article, we'll explore how enums contribute to bundle bloat, why Angular's build tools struggle to optimize them, and which alternatives you can use to write cleaner, faster, and more efficient code. An enum is a TypeScript feature that lets you define a set of named constants. For example: export enum UserRole { Admin, Editor, Viewer } Under the hood, this compiles to something like: "use strict"; var UserRo…  ( 5 min )

🧩 Implementation: @Injectable() export class DestroyService extends Subject { ngOnDestroy() { this.next(); this.complete(); } } 🧩 Question: ngOnDestroy() in this pattern? Even though DestroyService is a service and extends Subject, how does Angular still invoke ngOnDestroy()? 💡 Answer: Even though DestroyService extends Subject (which is not a component or directive), Angular still calls its ngOnDestroy() method if the service is provided at the component level. 🔑 Why ngOnDestroy() Gets Called in a Service ✅ Angular will call ngOnDestroy() if: The class implements OnDestroy AND it is a provider on a component or directive Example: @Component({ Then Angular treats the service like a directive-level provider, and because it has ngOnDestroy(): 🧠 Why It Works Even Though It Extends Subject Subject has no ngOnDestroy(). That's fine. You're extending Subject and adding ngOnDestroy() yourself. Angular doesn’t care that it extends Subject — it just sees: “This class was provided in the component” “It has ngOnDestroy()” ✅ Call it when the component is destroyed 🔁 Summary DestroyService is a service, but it's scoped to the component using providers: [DestroyService] It has a custom ngOnDestroy() method Angular calls ngOnDestroy() on component-scoped providers So you get an automatic, injectable "destroy notifier" for use with takeUntil() This is a neat Angular trick that combines: Lifecycle hooks Dependency injection RxJS into a reusable, composable unsubscribe mechanism.

The CSS Box Model is one of the most important concepts in web design 🧱. It describes how elements are structured on a webpage — every HTML element is treated like a box with layers: content, padding, border, and margin. 💡 What I Made I created a simple webpage using HTML and CSS ✨. It shows a box with the message "Hello Kts". You can view the live demo here: The design is simple but effective — a colored box with space inside and outside, and a border to highlight the shape. 🧠 How the Box Model Works in My Project: Margin: It adds space outside the box (like a buffer from the edges) ➡️ Padding: It adds space inside the box around the text, making it look neat 🧍‍♂️ Border: This creates a clear outline around the box ⚫ Background color: I used a brown background to make the box stand out 🟤 🚀 Why It Matters?

This is a submission for the Amazon Q Developer "Quack The Code" Challenge: That's Entertainment! I built a text adventure game inspired by the history of ancient Pompeii. I believe my text adventure game differentiates itself by adding new features to the UI as you progress through the game.

In this article, we will explore why Go allows type comparisons that might initially seem surprising, particularly in instances like comparing an integer to a string. We'll explain the underlying mechanisms of Go's type system and how the language handles such comparisons without raising errors or panics. Understanding Go's Type System Go is a statically typed language, which means that the types of all variables are known at compile time. When you define a variable, its type must be explicitly declared or inferred, leading to a robust type safety framework. However, Go introduces a unique feature with the any type, which can hold a value of any type. This flexibility plays a crucial role in our example. The Role of the any Type In your provided code, we see the variable hello is declared …  ( 5 min )

In the competitive world of e-commerce, monitoring prices on platforms like Amazon is crucial for businesses and savvy shoppers alike. However, scraping data directly from such websites can lead to IP bans and access restrictions. To mitigate these risks, using Python in conjunction with proxy IPs offers a safe and effective solution for price monitoring. Why Use Proxies for Amazon Price Monitoring? Anonymity: Proxies mask your real IP address, making it difficult for websites to track your scraping activities. import requests proxy = { http://your_proxy_ip:port", http://your_proxy_ip:port" def get_price(url): # Find the price element (this may vary based on the product page) url = 'https://www.amazon.com/dp/your_product_id' Static and Residential IPs: These are less likely to be flagged by Amazon.

连续分享了几天的Uniapp跨平台开发鸿蒙应用教程的文章，相信大家对跨平台开发已经有了初步的了解，今天分享一下跨平台开发中的自定义导航栏。 在Hbuilder的初始化项目中是自带了导航栏的，这是一个全局的导航栏，它的样式设置和修改是在全局的配置文件pages.json中进行。 现在打开pages.json文件，在globalStyle中有一些关于导航栏的属性，我们尝试修改一下： { "pages": [ //pages数组中第一项表示应用启动页，参考：https://uniapp.dcloud.io/collocation/pages ], "globalStyle": { 然后看到导航栏已经发生了改变： 这样的修改很方便很便捷，但是好像只有颜色和文字这些基础的属性可以修改，很多时候我们需要在导航栏上添加一些组件，比如按钮或者搜索框。 对于这种情况，uniapp也提供了相应的设置方案，还是在pages.json文件中，当我们需要为某一个页面的导航栏添加组件，就在对应的path路径下设置style，style中有个titleNView属性就是为导航栏添加自定义组件，像这样： "path": "pages/index/index", 但是幽蓝君亲测这种设置方式在浏览器运行时可以正常显示，在鸿蒙中是无效的： 所以在鸿蒙开发中我们需要自己定义导航栏。 再次回到pages.json文件，这次将navigationStyle设置成custom，作用是取消原生的导航栏： "path": "pages/index/index", 然后打开需要自定义导航栏的页面，我这里就直接在首页index.vue中操作，实现逻辑比较简单，就是在页面顶部添加一个导航栏大小的组件，然后在其中添加搜索框，相关代码如下： style="width: calc(100% - 40px);background-color: white;height: 35px;padding: 0px 10px;border-radius: 18px;" .custom-nav-bar { / background-color: #f8f8f8; 导航栏背景色 / 其他样式属性 */ 看一下运行效果： 今天就以添加一个搜索框为例，大家如果需要自定义其他的样式也是类似的实现方式。 以上就是uniapp跨平台开发鸿蒙应用中的自定义导航栏，感谢大家的阅读。  ( 3 min )

Most people think hacking is just about tools, code, or some flashy terminal with green text flying by. But that’s not what makes a real hacker. Let me tell you what really matters—the part only 1% truly understand… Forget the tools for a second. Real hacking starts when you ask the questions nobody else is asking: "Why does this work like that?" "What happens if I try something they didn’t expect?" "What’s behind this system they don’t want me to see?" It’s about curiosity. Obsession. Even rebellion. Not following tutorials step-by-step, but breaking patterns and learning how systems truly work under the surface. I’m teaching myself Python and networking— Not because I want to show off, but because I want to understand how the internet and machines actually think. I’m not here to be just another script kiddie. I’m building a foundation. Quietly. Daily. I don’t want fame. I don’t want likes. I want leverage. I want to be the kind of person who sees through the system—and knows how to bend it. A silent weapon. Sharp, skilled, and always learning. Are you learning just to pass exams? Or are you learning to break limits? Be real with yourself. The world’s already full of followers. We need more builders, breakers, and thinkers. If you feel that fire too—the curiosity, the hunger to really understand—drop a comment. Tell me what you're working on. I’m still early in my journey, but I’m in it for real. Let’s learn. Let’s grow. Let’s hack.  ( 3 min )

Introdução Com a expansão dos serviços on-line, surge uma demanda cada vez maior por sistemas responsivos, performáticos e de alta capacidade de escalabilidade. O uso da programação assíncrona se mostra muito eficaz na obtenção destes atributos de qualidade durante o desenvolvimento de um software. Este artigo busca mostrar os benefícios e os contrapontos do uso da programação assíncrona em Python em sistemas "I/O-bound" (altamente dependentes de input e output) e outras tarefas que necessitam de execução paralela. Conceitos de programação assíncrona Computadores executam softwares de forma sequencial, isto é, uma instrução após a outra. Um software geralmente realiza múltiplas tarefas, e nem sempre faz sentido esperar que uma tarefa termine antes de iniciar a próxima (SKVORTSOV, 2021). Se…  ( 5 min )

RESUMO Palavras-chave: Arquitetura REST. Sistemas distribuídos. API. HTTP. Serviços Web. 1 INTRODUÇÃO 2 DESENVOLVIMENTO De acordo com Stein Junior (2021), REST surgiu da necessidade de criar interfaces simples e eficientes para a comunicação entre sistemas, principalmente via web. O autor afirma que "o objetivo era criar interfaces simples, escaláveis e independentes, facilitando a comunicação entre sistemas distribuídos por meio do protocolo HTTP" (STEIN JUNIOR, 2021, p. 10). A arquitetura REST é baseada na manipulação de recursos — objetos ou entidades de informação — que são identificados por meio de URIs (Uniform Resource Identifiers) e manipulados utilizando métodos HTTP padronizados, como GET, POST, PUT e DELETE. Fielding (2000) ressalta que uma das principais características do REST…  ( 6 min )

Introduction In the world of numerical computing, transitioning from NumPy to JAX can offer significant performance benefits thanks to JAX's Just-In-Time (JIT) compilation and optimizations for GPU acceleration. However, this transition isn't always smooth for all operations, particularly for those that are heavily transformation-based, such as broadcast_to and moveaxis. In this article, we will explore why these functions may perform slower in JAX compared to NumPy and discuss best practices to optimize their usage. Understanding the Performance Discrepancy Why JAX May Be Slower for Basic Operations The performance of JAX can vary significantly depending on the operations being performed. While JAX is designed for efficient numerical computation and can excel in larger batch sizes and com…  ( 5 min )

Let’s not sugarcoat it—workflow automation should be simple. You sketch out a flow, wire up a few APIs, slap in a trigger, and boom: your job runs itself while you sip coffee. Except… not really. In reality, automation breaks. It misfires. It fails silently. And if you’re building workflows without a plan (I’ve done it), you’ll spend more time debugging than you ever saved. So here are 5 workflow automation mistakes I’ve run into—plus how I fixed them using Martini, a low-code automation platform that somehow gets it. 1. Only Building the Happy Path Raise your hand if you’ve built an automation that worked perfectly—until the first error. I’ve done it. Then I spent the next hour trying to figure out why a webhook timed out and brought down the entire flow. ✅ Fix: Build for failure first.…  ( 4 min )

How to Send Traces Using Scala and OpenTelemetry When working with distributed systems, traceability is crucial for understanding system behavior. If you are using Scala and OpenTelemetry to send traces, you may encounter some challenges, particularly if your traces are not appearing in the tracing backend like Zipkin or Tempo. Why Might Traces Not Be Sent? Traces not appearing in your tracing backend can be attributed to several issues. These issues might stem from misconfiguration in your OpenTelemetry setup, lack of proper attributes, or even potential threading issues with Scala. It’s essential to verify that the OpenTelemetry collector is up and running and that the endpoint is correctly configured, which you have indicated is ready. In Scala, the ThreadLocal context propagation can b…  ( 5 min )

This is a submission for the Amazon Q Developer "Quack The Code" Challenge: Crushing the Command Line I created envguardr, a CLI tool that validates environment variables at build time. It’s useful for projects where .env files or runtime checks aren't enough. It handles types, required fields, and default values, but I felt it needed more flexibility. To address that, I enhanced the underlying validation package valitype by adding support for custom validators. This was one of the ideas suggested by Amazon Q Developer during the challenge. That single improvement unlocked a range of advanced use cases. Install envguardr globally: $ npm install -g envguardr Create an env.schema.js file with custom validation logic: module.exports = { API_KEY: { type: 'custom', validator: (v) => /^[a-z0-9]{16}$/.test(v || ''), errorMessage: 'API_KEY must be 16 alphanumeric characters', required: true } } Then run: $ envguardr validate env.schema.js envguardr with a custom schema validation for API_KEY: https://github.com/fontebasso/valitype https://github.com/fontebasso/envguardr This challenge was my first experience with Amazon Q Developer, and I was genuinely impressed. It’s exactly the kind of tool I always felt was missing for developers working with AI. Amazon Q Developer was able to read my codebase, understand its context, and assist in meaningful ways. It helped me improve typing, write better tests, fix subtle lint issues, and explore useful new features. From the several improvements it suggested for valitype, I chose to implement custom validators. That feature alone made envguardr much more powerful, giving it the flexibility needed for advanced configuration validation.  ( 3 min )

In Perl programming, naming conventions for symbol table entries can seem confusing at first glance, especially when we encounter entries like Test_two and A_Package::Test_one. In this article, we will explore the distinctions between these two styles of naming and how they impact the scope and accessibility of your subroutines. Understanding Symbol Tables in Perl In Perl, every package has its own symbol table, which serves as a collection of all the symbols (subroutines, variables, etc.) defined within that package. This allows for the organization of code into different namespaces, ensuring that subroutine names do not clobber each other in larger applications. The Significance of Test_two When we define a subroutine using the name Test_two, like this: *{"Test_two"} = sub{"Testing Two…  ( 4 min )

Gland: Beyond Protocol-Agnostic Hey everyone, I’m back again with another update from the world of Gland — and this one is kinda big for me. So far, I’ve talked a lot about Gland being protocol-agnostic. But recently, something shifted. Gland is not just protocol-agnostic anymore — it’s kinda framework-agnostic too. What does that even mean? Let’s be real: right now Gland doesn’t care whether you're using Express, Fastify, Hono, or literally anything else that can act like an HTTP server. You can swap them in and out with minimal effort. And I’m not talking about some theoretical plug-and-play thing. I mean actual working code. Take this simple example: glandjs/gland/main/samples/01-simple/src/main.ts In this setup, I’m using Express. But if you want Fastify instead? Just do this: async fu…  ( 5 min )

JavaScript is a single-threaded, synchronous programming language at its core, but it handles asynchronous operations through clever mechanisms like the event loop. To truly understand how JavaScript works under the hood, you need to grasp two fundamental concepts: execution context and the call stack. An execution context is an abstract concept that holds information about the environment where JavaScript code is executed. There are three types of execution contexts in JavaScript: Global Execution Context: Created when the JavaScript engine first starts executing your code Function Execution Context: Created whenever a function is invoked Eval Execution Context: Created inside an eval function (rarely used) Each execution context has two phases: Creation phase Execution phase During the c…  ( 5 min )

🚀 Stepping Into the Cloud: My First Tech Internship I’ll be working remotely as a Cloud Engineering Intern at a startup called Pledged. They’re doing some really cool work helping universities and colleges manage their partnerships with external companies. Basically, they give schools one simple platform to track and organize all their business relationships — no more messy spreadsheets. Think of it like a behind-the-scenes CRM for higher education, and I get to help build it. What’s even more exciting? The tech stack. I’ll be working with: TypeScript Tailwind CSS React Router Vite Node.js Docker Microsoft Azure Yes — full-stack cloud engineering with a taste of containerization and cloud infrastructure. I’ll be starting out on front-end tasks, but eventually I’ll get to dive into cloud stuff too. With all the buzz around cloud computing, I can’t wait to roll up my sleeves and get my hands dirty in Azure. 🧠 How I’m Preparing i took an IBM JavaScript course on Coursera. Followed a Scrimba course to brush up on my JS fundamentals. Built a few practice projects to get comfortable with React (since I’ve never used it before). Started learning TypeScript ,also new territory for me, but I'm determined to hit the ground running. 😅 The Honest Truth I’ve heard people say your first tech internship humbles you. That thought stays in the back of my mind, and it does freak me out a bit. What if I struggle? What if I fall behind? But here’s what I do know: I’m giving it everything I’ve got.

One task you may not do every day, but will eventually face as an Angular Developer, is updating your Angular application's version. At first glance, it may seem simple — especially since the official documentation provides a step-by-step guide. However, that guide won’t cover everything you’ll encounter during a real-world migration. In this post, I’ll share key tips to help you upgrade your Angular project more efficiently and avoid common pitfalls. Before starting any migration, it's essential to have a solid Git workflow. I recommend using a Git Flow strategy: Keep your main branch stable and production-ready. Create a dedicated migration branch (e.g., migration/angular-17). Every time changes are approved on main, merge them into your migration branch to keep it up to date. This allow…  ( 4 min )

If you're working with Swift packages and need to convert your Swift project to an XCFramework, it's essential to follow a proper procedure since your customer requires it in that format rather than as a Swift Package Manager (SPM).

You would think that a small comment you made about your partner's outfit does not mean anything. However, that small comment has the potential to become a trauma for your partner. In fact, any comment that comes out of your mouth has the potential to scar your partner for life. Therefore, it is important to know yourself, know the evil and good side of your personality, know when each of those are in command of your speech. This knowledge will in turn make you a safe space for your partner, and will also make you someone that is able to prevent conflicts; "If I am aware of my mood I am able to manipulate my speech". Predict conflicts; "If I am at my worst mood the words that come out of my mouth will be harmful". Fix conflicts "I said certain things while I was not at my best cognitive ab…  ( 4 min )

When scripting in Bash, it's common to want to exit a script gracefully when an operation fails. This is essential for ensuring that your script does not continue to run in an erroneous state. In this article, we’ll explore how to exit a Bash script with a custom error message and discuss some common pitfalls that may arise in the process. Understanding the Basics of Exit Codes in Bash Bash scripts use exit codes to indicate completion status. A successful command returns an exit code of 0, while a failure returns a non-zero exit code. You can capture this behavior using conditional statements. For example, command || echo 'Error message' will output the error message if the command fails. Exiting Scripts on Command Failure If you want to exit the script when a non-existing command is invo…  ( 5 min )

In Ecuador, public data systems are becoming increasingly accessible, and developers have a unique opportunity to create tools that make this data more user-friendly. One such system is the ANT matrícula, which allows individuals to check the legal status of a vehicle by entering its license plate. This system is crucial for verifying vehicle registration, ensuring that taxes are paid, and checking whether there are any fines or restrictions on a vehicle. While the ANT does not provide a public API, developers can still create tools that simulate this functionality. For instance, a backend system can be built using technologies like Node.js, where users can input a license plate number and receive data about its registration status. This not only helps users avoid scams when buying a used car but also assists businesses in managing vehicle fleets or ensuring compliance with national regulations. However, it's important to follow ethical guidelines when accessing public data. Developers should ensure that personal data is never stored without consent and that scraping or data collection is done in compliance with legal standards. Creating tools based on the ANT National Transit Authority matrícula system brings significant value to users, especially by saving them time and offering an easy way to confirm the legal status of a vehicle without having to visit government websites. By building accessible and useful tools, developers can support transparency, safety, and efficiency in Ecuador's transportation system.  ( 3 min )

Understanding JavaScript Scope Through Unique Examples JavaScript scope is an essential concept that determines the accessibility of variables in different parts of your program. It helps you understand how variables are stored, where they can be accessed, and the lifecycle of these variables. Instead of using the typical let/const and function examples, let’s explore some fresh and unique scenarios to illustrate scope. Before diving into examples, let’s quickly define the types of scope in JavaScript: Global Scope: Variables declared outside of any function are in the global scope, which means they can be accessed anywhere in the code. Function Scope: Variables declared within a function are scoped to that function. They are not accessible outside of it. Block Scope: Variables declared …  ( 5 min )

Back in 2015, I wasn’t a developer (and still now). I had no formal training in coding. But I loved language learning tools, and I came across a neat pronunciation tool on a CD-ROM that came with the Oxford Advanced Learner’s Dictionary 9th Edition. I didn’t know it then, but trying to tinker with that app would kickstart my journey into programming — one that would eventually lead to building iSpeakerReact, a modern, open-source language learning tool powered by React and Electron. This post is a reflection on that journey — the mistakes, the revamps, and the little wins that kept me going. Before iSpeakerReact got its current name, it was just called iSpeaker. The tool originally started from the version on the CD-ROM of the Oxford Advanced Learner's Dictionary 9th edition in 2015. The o…  ( 6 min )

For years, create-react-app (CRA) was the go-to tool for spinning up new React projects. With a single command, you could scaffold a full React application complete with Webpack, Babel, ESLint, and more—all without touching a configuration file. But as the React ecosystem rapidly evolves in 2025, developers are asking: Is create-react-app deprecated? 🛑 The Short Answer: Not Officially, But Practically... Yes create-react-app has not been officially deprecated by its maintainers, it’s clear that active development has stalled. The React team has shifted focus to modern full-stack frameworks, and CRA is no longer the recommended way to start a new project. In other words: CRA still works, but it’s outdated, and better options now exist. 1. Stagnant Development 2. No Server-Side Rendering (S…  ( 5 min )

Payment is one of the problems in online business and Stripe quick emerged as the main payment system despite seen a fair amount of complains. After Marc Louvion released ByeDispute, I was intrigued that Stripe was not covering that and so ended up having a tunnel on card fraud and how Stripe works. Yes Stripe Radar exists and cover some fraud cases but does not cover everything and there have been complains of account flagging despite it or a modification of the fraud detection algorithms that blocks all in coming transactions without any possibilities to stop that. But also fake signups, trial/refund cycling, scraping, or promo code abuse. Enterprise tools are overkill, and DIY solutions eat up dev time. So I wonder if a more general product that check One-trial-per-user, detect disposable email and scraping, have behavioral bot checks, prevent promo/referral abuse and chargeback/refund patterns, ... Would actually be more interesting. When flagging you would get the reasons and the solution can be disactivated at any time. Maybe even a community side with common ban list on fraudulent payments or disputes. On top of that a dashboard to follow all of this. Would something like this be helpful or just more noise?

There’s something about this special sub-set in the integers set known as prime numbers, unyielding and yet endlessly mysterious. It feels deeply personal. As if the integers are whispering ancient secrets through a language only a few are tuned to understand. Where others have seen chaos, I see some scattered patterns beckoning us to listen more differently and closely. This is my journey, not a conclusion, but a conjecture, a set of observations, a map for others and me to carry further into the unknown. I began with a simple, persistent question: “How can I find the nth prime number?” At first glance, this might appear naïve. It is a question that has echoed through centuries, from the classrooms of ancient Alexandria to the chalkboards of modern-day mathematicians. But in that moment, …  ( 5 min )

Originally posted here In this short post, I'll share with you a simple pattern I use to centralize error handling for my HTTP handlers. If you've written any amount of Go HTTP servers, you've probably gotten tired of writing the same error handling code over and over again: func SomeHandler(w http.ResponseWriter, r *http.Request) { data, err := fetchSomeData() if err != nil { http.Error(w, "Failed to fetch data", http.StatusInternalServerError) log.Printf("Error fetching data: %v", err) return } // More if-err blocks... } This code is repetitive, error-prone, and clutters your handlers with boilerplate instead of business logic. The core idea is simple: change your handlers to return errors instead of handling them directly. package httperror im…  ( 4 min )

If you scroll down to the bottom of that page, you’ll see a list of the books that I’ve published. You’ll also see evidence of the problem I’ve been solving this morning. Books tend to have covers that are in a portrait aspect ratio. But the template I’m using to display them requires images in a landscape aspect ratio. This is a common enough problem. And, of course, we’ve developed a common way of getting around it. You’ll see it on that page. We create a larger version of the image (large enough to fill the width of where the image is displayed), apply some level of Gaussian blur to the image and insert a new copy of the i…  ( 5 min )

In software design, some objects are meant to be shared across the entire application. Think of a configuration manager, a database connection, or a logger. You don’t want to create multiple instances of these — just one that is reused everywhere. That’s exactly where the Singleton Pattern comes in. The Singleton Pattern ensures that a class has only one instance and provides a global point of access to it. It’s part of the Creational Design Patterns — patterns focused on object creation. Think of a government. There’s only one Prime Minister (ideally 😄). If you try to create a new one, it should refer to the existing one. Database connections Logging services Config/environment managers Thread pools Caching mechanisms class Singleton { constructor() { if (Singleton.instance) { return Singleton.instance; } this.timestamp = new Date(); Singleton.instance = this; } getTime() { return this.timestamp; } } // Usage const a = new Singleton(); const b = new Singleton(); console.log(a === b); // true console.log(a.getTime() === b.getTime()); // true class Singleton: _instance = None def __new__(cls): if cls._instance is None: cls._instance = super(Singleton, cls).__new__(cls) cls._instance.timestamp = "Created at instance creation" return cls._instance # Usage a = Singleton() b = Singleton() print(a is b) # True Controlled access to a single instance Saves memory (especially useful for expensive objects) Can be lazily loaded (created only when needed) Global state can be hard to test Can violate Single Responsibility Principle In multithreading environments, needs proper locking (especially in Java/C++) Keep it stateless if possible Avoid abusing it like a global variable Be cautious in multi-threaded apps (use locks/mutexes) The Singleton Pattern is a handy tool when you need exactly one instance of a class to coordinate actions across the system. Use it wisely and you’ll make your application more efficient and structured.  ( 3 min )

This can lead to inconsistent behavior, where the dropdown button only works after a second modal closure, suggesting that the D…  ( 4 min )

Setting up a monitoring stack in Kubernetes can be overwhelming if you're doing it for the first time. When I started working with Azure Kubernetes Service (AKS), I realized I needed better visibility into pod and node metrics — that’s when I turned to Prometheus and Grafana. In this post, I’ll walk you through the exact steps I took to get Prometheus and Grafana running on AKS, along with some lessons I learned along the way. ## 🔧 Why Prometheus + Grafana? Prometheus scrapes and stores time-series data from Kubernetes. Grafana gives you beautiful, customizable dashboards. Together, they provide powerful insights into your cluster’s performance. ## 🛠️ Prerequisites Azure CLI installed and authenticated kubectl configured to your AKS cluster Helm 3 installed A working AKS cluster bash helm repo add prometheus-community https://prometheus-community.github.io/helm-charts helm repo add grafana https://grafana.github.io/helm-charts helm repo update **Install Prometheus:** helm install prometheus prometheus-community/prometheus \ --namespace monitoring --create-namespace Install Grafana: helm install grafana grafana/grafana \ --namespace monitoring Access the Grafana UI: You can port-forward and access Grafana at http://localhost:3000: kubectl port-forward svc/grafana 3000:80 -n monitoring **Login using:** Username: admin Password: (from step 4) **📊 Importing Dashboards** Once inside Grafana, go to "Dashboards > Import" and use IDs from Grafana.com like: Kubernetes Cluster Monitoring: 315 Node Exporter: 1860 **💡 Lessons Learned** Always install Prometheus before Grafana if you want dashboards to auto-discover data sources. Use persistent volumes for Prometheus and Grafana in production. Set up alerts for critical metrics like pod restarts or high CPU usage. I’m planning to extend this by: Setting up AlertManager Integrating with Slack for alerts Enabling SSL and Ingress for Grafana Stay tuned! 👀  ( 3 min )

Introduction Redis is a fast, in-memory data store widely used for caching, message brokering, and real-time analytics. While Redis is incredibly efficient, network overhead can become a bottleneck when a large number of commands are sent sequentially. This is where Redis pipelining comes in. Redis pipelining allows a client to send multiple commands to the server without waiting for individual responses. The server processes the batch of commands and returns all responses in a single reply, significantly reducing the latency caused by round-trip communication. If you are struggling to remember redis commands then this cheatsheet might help you. Redis pipelining offers several advantages: Reduced Latency: By sending multiple commands in a single request, you cut down on network round-tri…  ( 4 min )

My Two Favorite MCP Tools - True Game Changers I've been building custom MCP tools for a month or so now, and just two of them have absolutely transformed how I work with Claude - they were the real 'aha!' moment for me and 'agentic' workflows. Now I get the MCP hype - at least partially :) So, here they are: these two tools essentially give me Claude Code functionality without the extra cost: list_repo_locations - A smart repository finder that uses fuzzy matching and helpful hints when matches aren't found issue_terminal_command - A controlled terminal execution tool, with a 'yolo' option to go beyond read-only mode Let me walk you through how to build these tools from scratch. By the end of this post, you'll have your own versions that you can customize to your heart's content! The c…  ( 8 min )

Gland: Beyond Protocol-Agnostic Genix ・ May 11 #opensource #programming #typescript #techtalks  ( 2 min )

Hey everyone, I’m back again with another update from the world of Gland — and this one is kinda big for me. So far, I’ve talked a lot about Gland being protocol-agnostic. But recently, something shifted. Gland is not just protocol-agnostic anymore — it’s kinda framework-agnostic too. What does that even mean? Let’s be real: right now Gland doesn’t care whether you're using Express, Fastify, Hono, or literally anything else that can act like an HTTP server. You can swap them in and out with minimal effort. And I’m not talking about some theoretical plug-and-play thing. I mean actual working code. Take this simple example: glandjs/gland/main/samples/01-simple/src/main.ts In this setup, I’m using Express. But if you want Fastify instead? Just do this: async function bootstrap() { const app…  ( 5 min )

Introduction For years, React Native developers working on iOS have relied on one command more than any other: cd ios && pod install This command has been a staple for managing native dependencies in iOS projects. But in 2025, React Native is moving away from it—and for good reasons. If you’ve recently seen a warning like: "Calling pod install directly is deprecated in React Native" ...you’re witnessing a significant shift in how React Native handles iOS builds. React Native is undergoing a significant transformation, and part of that involves reducing reliance on iOS-specific tools like CocoaPods. Here’s why: CocoaPods is great for iOS, but React Native aims for true cross-platform development. The new architecture favors tools that work seamlessly across iOS, Android, and beyond.

Finding the second highest average mark among students can be a common requirement in many applications that deal with student data. In this article, we will explore a solution to find the student with the second highest average mark without creating any new objects. We will be using Java streams and our custom Student class, which holds information about each student such as their average mark, first name, last name, and date of birth. Understanding the Problem To tackle this problem, we need to follow a few key steps. First, we need to sort the list of students based on their averageMark. Since we want to find the second highest average mark, it is essential to sort the list in descending order. According to the problem's requirements, if two students have the same average mark, we shoul…  ( 4 min )

Hi, my name is Anton. I'm a software developer specializing in cross-platform mobile development, currently working at a fintech company where I help build a neo-banking application. There's often debate about design patterns—do we really need them, or are they just outdated theory with little practical value in modern software development? I strongly disagree with the idea that patterns are unnecessary. In my view, having a solid foundation in theoretical concepts is extremely valuable. It's like recursion: you might not need it every day, but when you encounter a problem that is recursive in nature—like traversing a file system—you simply can't solve it effectively any other way. The same applies to design patterns. Some processes naturally fit certain patterns, and recognizing them allo…  ( 9 min )

How Your Code Became Someone Else’s Goldmine In the thickening jungle of AI innovation, Model Context Protocol (MCP) aggregation services are rising like monolithic temples, promising universal access to tools and automation. On the surface, it sounds utopian—a meritocratic open-source dream. Dig just below, however, and an unsettling reality emerges: these aggregators are monetising the sweat, intellect, and creative risk of thousands, sometimes millions, of individual developers. The winds have changed. Your code—once a byword for progress—has become just another commodity, fuelling centralised profit with little return for its creators. This is the story of a digital gold rush where the diggers now find themselves locked out of the vault. Remember the wild dawn of open source, when so…  ( 9 min )

We want to manage state, by dividing it into units and giving them a name. Attaching behavior to them is also a good option - and thus we have OOP. But let's not adopt it blindly - a critical examination is in order. OOP is there to promote Encapsulation, Polymorphism, Abstraction. What would be the optimal way of providing them? Encapsulation means exposing only as much information about the object as necessary to provide the service. All of the information that is exposed and used by clients, if it were to be changed, means that either the client has to change at the same time - or versioning would need to take place. This idea makes sense, and for a language to support it, it would need ways to mark visibility of fields and methods. Polymorphism means for the same object to exhibit diff…  ( 5 min )

It is difficult to claim that any system or program is completely secure. All of them may contain potential vulnerabilities - errors made during the development process - that can lead to serious consequences. Attackers often exploit such flaws. Information security companies continuously monitor vulnerabilities and update security databases. Their monitoring typically includes sources such as the U.S. Government’s National Vulnerability Database (NVD), security advisories, GitHub issue trackers, and open-source projects. To create malicious code, attackers use a variety of programming languages. Some are more popular in cybercriminal circles due to their ease of use, compatibility with specific systems, and the wide availability of libraries that help solve particular problems. The Most C…  ( 6 min )

The phrase “Click here” was once a cornerstone of internet navigation. It was ubiquitous across websites, often used as a direct instruction to users: simply click a link, button, or piece of text, and something new would unfold—whether it was a download, a page redirect, or a pop-up. In the early days of the internet, this phrase was essential, helping users navigate a relatively new and confusing online landscape. But today, “Click here” is seen as a relic, a remnant of simpler times that no longer meets the standards of modern web design and user expectations. In this article, we will examine how “Click here” came to prominence, why it has lost its relevance, and the evolution of web design that has led to the adoption of more sophisticated, user-centered alternatives.

Concurrency in Go Ismile Hossain ・ May 11 #go #programming #tutorial  ( 2 min )

❓ What is Concurrency? Concurrency is the ability of a program to manage multiple tasks at once. These tasks may not run exactly at the same time, but they are managed in such a way that it feels like they are happening simultaneously. Imagine you’re cooking dinner: You put water on the stove to boil. While the water heats up, you chop vegetables. Once it’s boiling, you add pasta. While pasta cooks, you prepare the sauce. You are switching between tasks. You're not doing everything at once, but you're switching between tasks efficiently to save time. That’s concurrency: smart multitasking, not true parallelism (which involves tasks running at the exact same time on multiple CPU cores) In Go, concurrency means: Your program runs multiple tasks (functions or processes). Each concurrent ta…  ( 19 min )

When you send a message over the internet—whether it’s a cat meme, a video stream, or a DNS lookup—it’s traveling through layers of protocols. Two of the most important transport-layer protocols in this stack are TCP and UDP. While TCP gets a lot of the spotlight thanks to its reliability and widespread use in web traffic, UDP (User Datagram Protocol) is the unsung hero behind many real-time and low-latency applications. In this post, we’ll demystify what UDP is, how it works, and why developers choose it despite its nickname: the "Unreliable Datagram Protocol." UDP is one of the core protocols of the Internet Protocol (IP) suite. It was introduced in 1980 as a lightweight alternative to TCP. UDP operates on top of IP and is used to send short messages called datagrams. The key difference?…  ( 4 min )

Understanding getHashCode() in C# When working with various controls or items in C#, particularly in Windows Phone 7 (WP7), you might encounter the getHashCode() method. This method is an integral part of the object class, allowing objects to produce a hash code, which is a sequence of numbers that computably represents the object. You may wonder if this hash code can uniquely identify an item like a picture or a song on your device. In this article, we will delve into what a hash code is and how getHashCode() works within the context of C#. What is a Hash Code? A hash code is a numerical value produced by a hash function, which maps data of arbitrary size to fixed-size values, usually for efficient data retrieval. It's a way to summarize data, which means that a unique piece of data may p…  ( 5 min )

前两天的文章内容对uniapp开发鸿蒙应用做了一些详细的介绍，包括配置开发环境和项目结构目录解读，今天我们正式开始写代码。 入门新的开发语言往往从Hello World开始，Uniapp的初始化项目中已经写好了一个简单的demo，这里就不再赘述，我们直接从布局开始说起。 Uniapp的布局方式和鸿蒙原生语言ArkTs有所不同，但又颇为神似。 幽蓝君之前总结过，所有的布局方式无非只有三种，横向、竖向和层叠，其他所有的布局方式都由这三种衍生而来，Uniapp也不例外。 ArkTs中有Row()、Column()、Stack()、Flex()这几个基础的布局容器组件，更复杂一些的还有像List()、Grid()、Scroll()等等。 而在Uniapp中，基础的布局方式我们通常直接使用view容器来实现。比如我想要实现一个横向的布局，使用view容器，在view的样式中设置布局方式为row： 而到了纵向布局，只需要把布局方向设置column就行了： 接下来比较难的部分到了，对于层叠布局，ArkTs直接提供了Stack()容器，并且有对应的对齐方式可以直接设置，比较简单。但是uniapp并没有提供这种对齐方式，flex-direction中是不能直接设置层叠布局的。 我们可以使用postion属性来实现。postion的作用是设置定位方式，有static、relative、fixed、absolute集中方式，我们今天要说的是absolute。 absolute是一种绝对定位方式，是脱离了文档流、相对于父元素的绝对定位方式。 更详细一点解释就是不管它有多少同级别的组件，都不影响它以父元素左上角为原点的定位，同样的它也不影响别人，相当于悬浮在上层，使用偏移量来控制位置。比如下面这段代码： 所以如果需要层叠布局的两个容器都使用absolute定位，并且使用top、left、bottom、right来设置对齐方式，就实现了鸿蒙中的Stack()一样的功能： 这里可以使用z-index来设置谁在上一层，另外，绝对定位的父容器需要设置position: relative属性，否则子组件无法找到目标。 以上就是Uniapp开发鸿蒙的基础布局方式，感谢您的阅读。  ( 3 min )

Introduction to BlockingCollection and Memory Management In C#, the BlockingCollection class is a powerful tool for handling producer/consumer scenarios in a thread-safe way. However, when dealing with large objects that can vary in size significantly—like the ones you mentioned ranging from 10 MB to 700 MB—it's crucial to manage memory effectively to avoid OutOfMemoryExceptions. To achieve this, we need a customized collection that extends the functionality of BlockingCollection by allowing us to limit the total memory used by the items stored in it.

TypeScript offers powerful tools that help you write clean, scalable, and type-safe code. Two of the most useful features in this toolkit are Union Types and Type Aliases. In my latest YouTube video, I break down how to use these features effectively—even if you're just getting started with TypeScript. ✅ What You'll Learn ✅ What is a Union Type in TypeScript? ✅ How to use Union Types with function parameters ✅ What is a Type Alias and how to use it ✅ How to combine Union Types and Aliases ✅ Real-world use cases and code walkthroughs ✅ Common mistakes to avoid If you've ever found yourself repeating types or making your code harder to read, Union Types let you define a variable that accepts multiple types: let id: string | number; Meanwhile, Type Aliases allow you to give a custom name to a type: type ID = string | number; function printId(id: ID) { console.log("Your ID is:", id); } Combined, they make your code more readable, reusable, and easier to maintain. type SuccessResponse = { status: "success"; data: string; }; type ErrorResponse = { status: "error"; error: string; }; type APIResponse = SuccessResponse | ErrorResponse; function handleResponse(res: APIResponse) { if (res.status === "success") { console.log(res.data); } else { console.error(res.error); } } This is a clean, scalable way to handle multiple response types from an API. I walk you through all this and more in the full tutorial on YouTube: 👉 Watch on YouTube Whether you're building a small project or working with a large team, learning how to use Union Types and Type Aliases will make your TypeScript code more maintainable and developer-friendly.

Hello everyone! It’s been another productive month in the LFX Mentorship program with the CNCF Microcks project. This month, I focused on enhancing Microcks deployments on Google Kubernetes Engine (GKE) and improving documentation for cloud-specific deployment strategies. Additionally, I had the opportunity to present my contributions during the community meeting, where I encouraged others to contribute, provide feedback, and review the documentation. Asynchronous Options on GKE I worked on improving the Microcks GKE deployment by adding support for asynchronous protocols and securing the Microcks endpoint with TLS. Enabled Kafka-based async protocols with Helm and installed Strimzi for Kafka management. Secured the endpoint using cert-manager and Let's Encrypt for automatic SSL certificate provisioning. Deploying complex systems like Microcks with external Keycloak and MongoDB can sometimes lead to roadblocks. To address this, I created a TROUBLESHOOTING.md file in the repository. This document provides a set of common issues and solutions that developers may encounter when deploying Microcks on GKE, especially when integrating with Keycloak for authentication and MongoDB for data storage. Troubleshooting Guide I developed a GUIDELINES.md document that outlines the deployment process for Microcks across multiple cloud providers. The guidelines cover setting up infrastructure, deploying Keycloak, provisioning databases, and configuring Microcks with Helm. Common Guidelines Next month, I plan to: Deploy Microcks on Azure AKS and document the process. Add a Troubleshooting Guide for Azure deployment. Month two has been an exciting journey, contributing to Microcks with improvements in deployment, security, and cloud-specific guidelines. I’m excited to continue supporting the Microcks community and look forward to the next steps! Feel free to check out my contributions on the Microcks community repository  -  feedback and contributions are always welcome! See you in the next update! 👋  ( 3 min )

JSON (JavaScript Object Notation) is a lightweight data-interchange format that's easy for humans to read and write and easy for machines to parse and generate. It's one of the most widely used formats in web development, especially when working with APIs and server responses. JSON is a text-based format for representing structured data. It resembles JavaScript object syntax, but it's a string. Example JSON: { "name": "Alice", "age": 25, "isStudent": false, "skills": ["HTML", "CSS", "JavaScript"] } They look similar, but they are different: Feature JavaScript Object JSON Data Type Object String Can contain functions Yes No Comments Allowed Not allowed Quotes on keys Optional Mandatory JSON.stringify() Converts a JavaScript object into a JSON string. const user = { name: "Bob", age: 30 }; const jsonString = JSON.stringify(user); console.log(jsonString); // '{"name":"Bob","age":30}' JSON.parse() Converts a JSON string back into a JavaScript object. const jsonString = '{"name":"Bob","age":30}'; const user = JSON.parse(jsonString); console.log(user.name); // 'Bob' fetch('https://api.example.com/data') .then(response => response.json()) .then(data => { console.log(data); // Parsed JSON object }); Most APIs return JSON. Using .json() parses the response body into a JavaScript object. Forgetting to wrap keys in quotes in JSON: { name: "John" } // Invalid Correct: { "name": "John" } Using functions in JSON: JSON.stringify({ sayHi: () => "Hi" }); // sayHi will be removed JSON is used for storing and exchanging data. Use JSON.stringify() to convert objects to strings. Use JSON.parse() to convert strings to objects. It’s widely used in API communication. Tip: Use https://jsonformatter.org/ to format or validate JSON quickly.  ( 4 min )

This guide explains — in simple words — how to stay safe, what to watch for, how to recover if attacked, and why being aware is more important than ever. 🚨 Why Are Cyberattacks Rising Everywhere Global conflicts and wars often extend into cyber wars. Hackers are not just criminals — some are sponsored by governments. Everyday people are easier targets because they are often less protected. Criminals want easy money — and ordinary users are softer targets. Lack of awareness is the biggest weakness hackers exploit. No matter who you are — a student, a professional, a business owner, or a retiree — you are valuable online. Your identity, money, and personal data are what attackers seek. 🧨 Common Types of Cybe…  ( 5 min )

Clean Architecture is a great concept. It’s meant to help you write maintainable, modular, and scalable software. But too many developers treat it like a religion. They follow it blindly, stuffing projects with unnecessary layers, abstractions, and patterns. All in the name of “clean code.” Let’s be honest, Clean Architecture is often overused, not because the ideas are bad, but because people overengineer the implementation. Here’s an example of multiplying two numbers implemented with an absurd number of patterns: // overengineered-multiplier.ts // Interface interface IMultiplier { multiply(a: number, b: number): number; } // Singleton class MultiplierService implements IMultiplier { private static instance: MultiplierService; private constructor() {} static getInstance(): Mu…  ( 5 min )

Opinion by: Sean Li, co-founder of Magic Labs Crypto markets run 24/7. Human traders don’t. As AI agents begin to manage liquidity, optimize yield, and execute trades at all hours, they’re quickly becoming essential infrastructure for decentralized finance’s (DeFi) future. While AI agents are evolving from niche tools for quant traders into mainstream financial operators, they’re rapidly outpacing the wallets meant to secure them.  Advancements in account abstraction and smart contract wallets have emerged, but most DeFi platforms still predominately rely on externally owned account wallets that require manual approvals at every step. Early-stage programmable solutions exist but remain fragmented, costly on layer-1 networks and adopted by only a tiny fraction of users. As AI agents increas…

Ethereum’s latest network upgrade, Pectra, introduced powerful new features aimed at improving scalability and smart account functionality — but it also opened a dangerous new attack vector that could allow hackers to drain funds from user wallets using only an offchain signature. Under the Pectra upgrade, which went live on May 7 at epoch 364032, attackers can exploit a new transaction type to take control of externally owned accounts (EOAs) without requiring the user to sign an onchain transaction. Arda Usman, a Solidity smart contract auditor, confirmed to Cointelegraph that “it becomes possible for an attacker to drain an EOA’s funds using only an offchain signed message (no direct onchain transaction signed by the user).” At the center of the risk is EIP-7702, a core component of the …

Hackers drained over $2.15 million from Mobius Token ($MBU) smart contracts on the BNB Chain in a targeted exploit detected early May 11, according to security firm Cyvers Alerts. The attacker deployed the contract from address 0xb32a53... at 07:31:38 UTC and initiated the exploit at 07:33:56 UTC, draining funds from the victim wallet 0xb5252f... Cyvers confirmed to Cointelegraph that the attacker used contract 0x631adf... to execute a series of malicious transactions. The smart contract drained 28.5 million MBU tokens and converted them into stablecoins, resulting in a net loss of $2,152,219.99 for the victim. In total, the attacker stole 28.5 million MBU tokens and converted them to $2.15 million worth of USDT. Cyvers labeled the exploit as “critical” and noted the attacker’s use of suspicious contract code and abnormal transaction patterns. The attacker’s wallet remains active and has retained the stolen funds as of publication. Mobius Token’s team has not yet released an official statement. “Two minutes prior to the exploit, our system identified a deployment of a malicious smart contract that eventually targeted the Mobius Token smart contracts,” Cyvers wrote on X.

The investigator later confirmed that the transfer was a social engineering attack targeting an elderly individual in the United States.  Magazine: 12 minutes of nail-biting tension when Ethereum’s Pectra fork goes live

Altcoin markets are flashing early signs of a breakout, with several analysts calling for a potential surge over the next few months. Crypto commentator Mister Crypto predicts the next 3 to 6 months could be “life-changing,” suggesting daily gains of up to 40% may soon become the norm. In a May 11 post on X, he pointed to a chart from BlockchainCenter.net that shows whether the crypto market favors Bitcoin (BTC) or altcoins. When the index is below 25, it’s considered “Bitcoin Season,” meaning Bitcoin is outperforming most altcoins. When it’s above 75, it’s “Altcoin Season,” meaning altcoins are doing better than Bitcoin. Currently, the chart shows a breakout from a downward trend just below the 29 mark, suggesting a possible shift away from Bitcoin dominance. This breakout hints that altc…

Coinbase CEO Brian Armstrong said his company had considered adopting a Bitcoin investment playbook like Michael Saylor’s Strategy on multiple occasions, but decided against it each time out of fear that it would kill the firm’s crypto exchange, Bloomberg reported. “There were definitely moments over the last 12 years where we thought, man, should we put 80% of our balance sheet into crypto — into Bitcoin specifically,” Armstrong revealed to Bloomberg in a May 9 video call. Armstrong said the Bitcoin (BTC) strategy could have risked the company’s cash position and potentially killed the crypto exchange. “We made a conscious choice about risk,” he added. Coinbase Chief Financial Officer Alesia Haas, who also attended the video call, added that the firm didn’t want to be seen as directly com…

Abstract Introduction The conventional model of web application development separates frontend and backend responsibilities into different teams, skillsets, and codebases. Frontend developers manage UI and client-side logic, while backend developers handle server-side processing, API creation, data storage, and security enforcement. However, this division can lead to longer development cycles, coordination challenges, and duplicated logic across layers. A new paradigm is emerging—one in which frontend developers can declaratively define backend logic using frontend tools and syntax. This shift is enabled by modern platforms that offer serverless scalability, secure permission management, and efficient request/response handling under the hood. This approach doesn't eliminate the need for ba…  ( 5 min )

Introduction to UDF and Vector UDF in Spark 3 In Spark 3, the advent of vectorized UDFs (User Defined Functions) has created a significant advancement in how operations on DataFrames can be efficiently executed. Understanding the differences between traditional UDFs and the newer vectorized UDFs is crucial for optimizing performance in big data processing. What are User Defined Functions (UDFs)? Traditional UDFs User Defined Functions, commonly referred to as UDFs, are functions written by users to extend the functionality of Spark. They allow you to perform custom operations on DataFrames and Datasets. For example, if you want to apply a complex transformation that is not available out-of-the-box in Spark, a UDF can be created in languages like Scala or Python. How Traditional UDFs Work T…  ( 5 min )

Introduction When working with Entity Framework Core (EF Core) in C#, managing relationships between entities is crucial. In this scenario, we have a case where a department can have multiple users, and when a user is assigned a new department, we need to ensure the previous department is deleted if it has no users left. This is a common requirement in applications that handle organizational structures. Why the Department Query Might Not Reflect Updates In your situation, you are attempting to update a user's department and then immediately check if the previous department has users left. You notice that even though the update reflects in the database, the department load returns stale data. This issue can arise due to EF Core’s change tracking behavior and how it interacts with the databa…  ( 5 min )

Libuv describes itself as a multi-platform support library with a focus on asynchronous I/O. It is widely used in many web servers (e.g., Kestrel) and runtimes such as Node.js and Python (via uvloop). As of Zig 0.14.0, there is no native async I/O, so you must work directly with threads or create your own async API using OS primitives like epoll or kqueue. In many cases, you would likely choose a cross-platform library rather than implementing your own async API. That’s where using libuv, libevent, or libxev (written in Zig) becomes useful. This guide will show you how to use libuv from your Zig project. I’ll start with a basic Zig project to demonstrate how this works. It will be a simple app that runs some timers. We’re going to use the package from github.com/allyourcodebase/libuv to bu…  ( 5 min )

An open-source project called Deep-Live-Cam is gaining traction on GitHub — and for good reason. With just a single still image, it can mimic anyone’s face in a live video call. In real-time. Running locally. No cloud required. The implication is clear: you can no longer trust a video call at face value. So here’s the question: how do we verify identity in a world where faces can be forged on demand? While many react with fear or disbelief, I see only one viable answer: digital signatures. For years, I’ve been saying: we should encrypt everything — files, messages, infrastructure. But now, that’s not enough. We need to start signing everything. Digital signatures ensure authenticity. They prove that something really came from who claims to have sent it and hasn’t been tampered with. We already sign emails, source code, and software packages. Why not apply the same principle to real-time streams? Imagine a video call cryptographically signed with the speaker’s GPG key. Even if the face looks convincing, if the signature doesn’t verify, you know something’s off. I sign every HTML page on my personal website with my GPG key. Not because I’m paranoid — but because I believe security should be a mindset. Don’t trust. Verify.  ( 3 min )

Understanding the Challenge You might be facing an issue where your progress bar component does not rerender despite the state updates from useState. This can be confusing, especially when the console confirms that the state is updating. The problem often resides in how Reac's reconciliation process manages component updates and how state is propagated to child components. Setting Up the WebSocket Connection To facilitate real-ti…  ( 5 min )

If you're learning C# or .NET development, you might encounter this frustrating error: One or more errors were encountered while creating project ConsoleApp3. The generated project content may be incomplete. The SDK 'Microsoft.NET.Sdk' specified could not be found. I faced exactly this issue during my early days learning C#. After multiple attempts, I finally found a solution that worked reliably for me: The root cause appears to be that the official .NET SDK installer sometimes doesn't correctly set up the SDK on your system. Even after installation, the command dotnet --list-sdks might return an empty list, which indicates the SDK isn't properly recognized by your system. Here's what worked for me: Download the Binaries Manually: Go to the official .NET SDK downloads page. Instead of downloading the installer, choose the "Binaries" option. This will give you a .zip file containing the SDK files directly. Extract and Copy Files: Extract the downloaded .zip file to a temporary location. Replace SDK Contents: Navigate to: C:\Program Files (x86)\dotnet\ Delete or back up existing contents, then paste the newly extracted SDK binaries into this folder. Verify Installation: Open a new Command Prompt or PowerShell window and run: dotnet --info You should now see details about the SDK and runtime versions installed. This solution manually ensures that the SDK files are correctly placed and recognised by your system, bypassing the potential issues caused by the automated installer. If you're still experiencing issues after following these steps, consider checking your environment variables to ensure C:\Program Files (x86)\dotnet\ is correctly listed in your system PATH. I hope this guide helps anyone stuck with this annoying issue! If you find additional solutions or improvements, please share them—I'm still learning and would love to hear from you.  ( 3 min )

gRPC (Google Remote Procedure Call) is a high-performance, open-source framework for making remote procedure calls. Unlike traditional REST APIs that use HTTP/1.1 and JSON, gRPC leverages HTTP/2 and Protocol Buffers for more efficient communication between distributed systems. This modern approach offers significant advantages in terms of performance, type safety, and code generation capabilities. When working with gRPC, you need to understand the fundamental components and workflow that differentiate it from other API communication methods. The process begins with defining your service interface using Protocol Buffers (protobuf) in a proto file, which serves as a contract between client and server. This definition is then compiled into language-specific code that handles all the underlyin…  ( 5 min )

You're correct in observing that the continue statement should skip the remaining commands in the loop and jump to the next iteration. So, why isn’t it working as expected in your case? Understanding the Issue The primary reason the continue statement may not be functioning as you expected lies in the structure of your loop and the way Bash interprets commands. A common mistake is how command substitutions and pipes are handled in Bash scripts. When you use a pipe (|), the commands are run in separate subshells. This means the continue statement is scoped to…  ( 4 min )

As software engineers, our job isn't just writing features or fixing bugs. We're responsible for improving the processes around software and help teams move faster, safer, and more consistently. That means asking questions like: Can we reduce repetitive tasks? Can we encode best practices so new team members don't guess? Can we lower the mental load of starting new features? For Angular projects, Schematics is one of the best tools to operationalize these improvements. It lets you automate architecture, encode standards, and enforce patterns. A schematic in Angular is a set of instructions that tells the Angular CLI how to generate or transform code. Think of it as a script that can: Create new files using templates. Update existing code (e.g. add a component to a module). Enforce consiste…  ( 4 min )

Why Psycopg3 1. No upcoming features for psycopg2 Psycopg2 is not expected to receive new features anymore From psycopg2 Pypi description: The psycopg2 package is still widely used and actively maintained, but it is not expected to receive new features. Psycopg 3 is the evolution of psycopg2 and is where new features are being developed: if you are starting a new project you should probably start from 3! Psycopg3, being the successor of psycopg3, presents a familiar interface for everyone who has used Psycopg 2 or any other DB-API 2.0 database adapter, but allows to use more modern PostgreSQL and Python features.(cite) Django starts to support psycopg3 in Django 4.2. And Django 5.1 also introduces connection pooling with psycopg3, that gives us the incentive to upgrade bot…  ( 5 min )

Hi devs — I recently launched a platform called aimodeling.me, and I’d love to share what it does, how it works, and why I built it. In short, it lets you create a realistic AI model of yourself — your own "digital twin" — from just a few selfies. After that, you can generate endless photorealistic images of you in any scenario, outfit, or setting you can describe. We’re all used to AI image generators now, but most of them produce generic faces or imaginary people. I thought: what if we flipped that? What if you could put yourself in those scenes? Professional photoshoots are expensive, awkward, and static. I wanted a way to generate high-quality, personalized photos for myself (for social media, bios, content creation, etc.) without constantly needing to step in front of a camera. So I b…  ( 4 min )

Working in Japan under the constraints of a work visa means there’s really not much you can do besides your day job. About the only other option is saving money and investing through NISA... Even if your company allows side jobs, you still need to apply for “Permission to Engage in Activity Other Than That Permitted Under the Status of Residence,” and possibly register and communicate with the authorities. Just thinking about all that paperwork makes me not want to bother. After all, the main goal is to build a life where I can live long-term in a place I truly want to be — for me, that’s Japan. So in reality, my daily life basically revolves around working and studying to prepare for a career move. I won’t deny that this kind of routine gets a bit dull over time. I just want a little more freedom, especially since both language learning and job hunting take so much time. Anyway, I need to hit my goal as soon as possible so I can finally enjoy the freedom I want in Japan!  ( 3 min )

Getting the names in your code right is crucial — it makes your code easier to read, maintain, and debug. But honestly, it’s not always obvious what makes a name good or bad, especially when you’re reviewing someone else’s code. In this post, I’ll share my mental checklist for reviewing names during code reviews. It’s based on principles from Clean Code book, but expressed in a straightforward, practical way so you can start applying it today. The name should make the purpose of the variable, function, or class obvious. It should not require you to dig through the code or run around to figure it out. Be descriptive to provide enough context if it helps clarify the intent. Avoid vague or overly broad names. // Problematic List data; // what kind of data? Better: Clear purpose List…  ( 4 min )

Abstract Alzheimer's disease (AD) represents a significant global health challenge. This paper proposes an experimental approach for early AD detection using Electroencephalography (EEG) signals processed through an innovative deep-learning architecture. I suggest a channel-frequency-based attention model that effectively captures spectral features across different brain regions. This model uses depthwise convolutions, squeeze-and-excitation blocks, and spatial dropout regularization to efficiently learn patterns within EEG data. The dataset has 19-channel EEG recordings from subjects with Alzheimer's, healthy controls, and frontotemporal dementia. The model shows 83.81% accuracy, which tells us about its potential. Alzheimer's disease (AD) is a progressive neurodegenerative disorder tha…  ( 10 min )

If you're using fprintd for fingerprint authentication on Linux and encounter this error after waking your system: Device reported an error during identify: Cannot run while suspended. …it likely means the fingerprint device fails to recover correctly after suspend or hibernate. You can fix this by restarting the fprintd service automatically after resume. Here's how: Create a file at /etc/systemd/system/restart-fprintd-after-suspend.service: [Unit] Description=Restart fprintd after suspend After=suspend.target hibernate.target hybrid-sleep.target suspend-then-hibernate.target [Service] Type=oneshot ExecStart=/bin/systemctl restart fprintd.service [Install] WantedBy=suspend.target hibernate.target hybrid-sleep.target suspend-then-hibernate.target Enable the service running this command: sudo systemctl enable --now restart-fprintd-after-suspend.service Now fprintd will restart automatically after suspend or hibernate, and your fingerprint sensor should work reliably again.  ( 3 min )
